ROTARY PULSE GENERATORThe ZCG can be direct-coupled to a machine shaft by means of a flexible
bellows, spring or rubber sleeve type coupler, etc., that allows for axial and radialmisalignment. They can also be coupled with instrument timing belts and pulleysor gears. The housing may be rigidly face-mounted with the 4, #8-32 threadedholes. The 3-wire shielded cable exits through a cord connector.LENGTH SENSOR
The length sensors are available in both Single Ended Shaft (ZFG) andDouble Ended Shaft (ZGG) versions, both of which include a Stainless SteelHandle Tube for mounting and 10 feet (3.05 M) of 3-wire shielded cable. Whenmounted to a Length Sensor Hinge Clamp Assembly (See Model LSAHC001)and coupled with one or two Measuring Wheels (See Measuring Wheels), a lowcost, versatile and highly accurate length measurement system can beconfigured.
LENGTH SENSOR MEASUREMENT ACCURACYFactors which affect measurement accuracy include Measuring Wheel

Conversely, soft, thick and elasticmaterials can present problems in obtaining true readings. Count or RateIndicators with “input scaling” can compensate for Measuring Wheel wear andmaterial elasticity and compliance errors. In addition, English/Metricconversions may also be accomplished.
Open Collector Output WiringThe ZCG, ZFG, and ZGG series of sensors have open collector outputs. An
open collector output brings the uncommitted collector of the encoderswitching device to the external world. Because the collector element is notassociated with the sensor supply voltage, the sensor output collector may be“pulled up” to external voltages (40 VDC max.) different than the encodersupply voltage. NPN open collector outputs are current sinking devices. Anoutput signal will not be generated unless a pull-up resistor is connected fromthe open-collector to the positive side of an external supply.

The units contain an L.E.D. light source and a photo sensor that scans a shaft-mounted, slotted disc. An internal pulse-shaping amplifier circuit delivers arectangular pulse signal from the current sinking output in response to the passingslots as it rotates. They can be direct-coupled to a machine shaft by means of aflexible-bellows, spring, or rubber sleeve type coupling that allows for axial andradial misalignment. They can also be coupled with light instrument timing-belts.Timing-belt drives also allow convenient gear-up or gear-down speed ratiochanges that can be useful for obtaining non-standard PPR rates.

When the desired output of a length sensor and wheel combination is either in feet or inch units, selectionof the proper combination is relatively straight forward. For example, with a 1-foot wheel circumference, a1 PPR Rotary Pulse Generator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1 pulse/inch); 100PPR would yield 100 pulses/ft; and 120 PPR would permit measuring to 1/10th of an inch (1/120th of a foot).
SELECTING APPROPRIATE WHEEL SIZE & PPR (Pulses Per Rev.) OF ROTARY PULSE GENERATOR
LENGTH SENSOR CONVERSION BRACKET (P/N LSCB1000)ADAPTS ZBG and ZBH ROTARY PULSE GENERATOR TO LENGTH MEASUREMENT
DESCRIPTIONThis conversion bracket allows the customer to assemble a custom length
sensor by purchasing the following items separately.1. Length Sensor Conversion Bracket (P/N LSCB1000)2. ZBG or ZBH with appropriate PPR and Single Channel or QuadratureOutput.3. One or two measuring wheels. Install OF & OK measuring wheels with setscrew hub facing ZBG shaft (as shown). Apply thread locking material to wheelset screw threads during installation to ZBG or ZBH shaft.4. Hinge Clamp Assembly (P/N LSAHC001)Note: To complete installation, insure guards, shields or other devices are inplace to protect personnel from rotating equipment.
The tubular arm length of this bracket, related to the wheel axis center-line ofthe ZBG or ZBH is 6.8" similar to the length sensors. The 10´ long, 4-wire,shielded cable (included with conversion bracket) has the same color coding asdescribed for the ZBG and ZBH cable P/N CCARPG01. Screws for mountingthe conversion bracket are included.
LENGTH SENSOR MEASUREMENT ACCURACYFactors which affect measurement accuracy include Measuring Wheel
accuracy and wear, and material conditions. Ideally, materials which are hard,thin and strong provide good readings, conversely, soft, thick and elasticmaterials can present problems in obtaining true readings. The great majority ofthese situations, where this effect is consistant, can be compensated for byapplying a multiplier to the quadrature output pulse train so as to obtain acorrected measurement. Counter or Rate Indicators with “input scaling” cancompensate for Measuring Wheel wear and material elastic and complianceerrors. In addition, English/Metric conversions may also be accomplished (SeeRLC catalog for more information).

The Length Sensor Hinge Clamp Assembly provides an easy method forattachment and mounting of the Length Sensors and LSCB1 ConversionBracket. The removable top on the solid zinc LSAHC mounting blockallows quick installation of the Length Sensor handle tube and providessecure clamping retention. The mounting block pivots freely in zinc rightangle brackets to allow mounting the assembly via clearance holes for 1/4"dia. bolts.
The lock washers must be used as indicated (between the bolt head andthe top clamp piece). Assemble the top clamp piece as follows.
1. Tighten both bolts so that the top clamp half draws down evenly onthe sensor tube.
2. Tighten the bolts until both lock washers are flat.3. Then turn each bolt an additional ½ to ¾ turn.

GENERAL DESCRIPTIONThe ZUK is a high performance unit that is ideal for fast revving motor mount
applications. This industrial strength model features the largest thru boreavailable in a 2.5" encoder, mounting directly on shafts as large as 1.125" (28mm.) The injection molded housing is grooved with “cooling fins”, and can takethe extreme heat of the motion control industry.
The ZUK comes equipped with a 3 point Flex Mount adapting to both 2.25"and 2.75" motor faces. It is also available with an optional “tether arm”mounting kits for additional motor compatibility.
This revolutionary encoder can also be adapted to various standard and metricsized motor shafts by using an accessory sleeve kit, or individual sleeves (Soldseparately).
Electrically the ZUK offers NPN open collector outputs, each limited to 100mA. The outputs are standard quadrature with index and are also available withquadrature reverse phasing for the typical motor drive controller application.The quadrature separation is 90° with output A leading output B for clockwiserotation. Output B leads output A for the reverse phased output, for clockwiserotation.
Open Collector Output WiringThe ZUK series of sensors have open collector outputs. An open collector
output brings the uncommitted collector of the encoder switching device to theexternal world. Because the collector element is not associated with the sensorsupply voltage, the sensor output collector may be “pulled up” to externalvoltages different than the encoder supply voltage (40 VDC maximum). NPNopen collector outputs are current sinking devices. An output signal will not begenerated unless a pull-up resistor is connected from the open-collector to thepositive side of an external supply. The same supply can be used for poweringthe unit and for the pull-up resistor.

MOUNTING INSTRUCTIONSMounting Kit Items Included:
4 ea. - 3/8" 16 x 1.0" Length Socket Head Cap Screws,Black Alloy.
4 ea. - 3/8" High Collar Spring Lock washer, Steel Zinc.1 ea. 3/32" Hex Allen Wrench, Long arm.
Note: The ZR encoder can mount to many types of C face devices. Inthese mounting instructions, we will refer to the device as a motor.
Step 1After carefully unpacking the unit, inspect to insure the motor
shaft is the correct size and free of all burrs or aberrations. Slide theZR Encoder over the motor shaft. DO NOT USE EXCESSIVEFORCE: There is a rubber O-ring in the Encoder locking collar thatwill provide a small amount of resistance as it engages the shaft. Ifthe encoder does not slide easily See Note 1 below.
Step 2Install the four 3/8" 16 x 1.0" socket head cap screws with lock washers
through the holes in the Encoder C face and tighten securely to the motor.
Step 3Insure the shaft locking collar is flush with the Encoder cover plate. Prevent
the motor shaft from turning (See Note 2 for additional information) andtighten the four 4-40 Allen head cap screws in the locking collar evenly in acrossing pattern. See Figure 1. Make sure the screws are securely tightened andthe front of the locking collar remains flush with the encoder cover plate. If thecollar does not turn true when the motor shaft is rotated, loosen the four screwsand repeat the procedure.
In Case of Difficulty:Note 1: Make sure the four 4-40 Allen head cap screws in the front of the
Encoder locking collar are loose and the collar is not cocked or jammed.Clean the shaft of any burrs using fine crocus cloth. The O- ring in theEncoder locking collar may need a small amount of additional lubrication.
Note 2: When tightening the screws in the locking collar avoid holding themotor shaft with anything that may scar or burr the shaft.

DESCRIPTIONThe Model ZR C-face encoder is a rugged, high resolution, high temperature
(100°C) encoder designed to mount directly on NEMA C-face motors. The ZRcontains a precision bearing and internal coupling that virtually eliminatesinaccuracies induced by motor shaft runout. This encoder is ideal forapplications using high performance AC vector motors.
The thru-shaft design allows fast and simple mounting of the encoder directlyto the accessory shaft or to the drive shaft of the motor, using the standard motorface (NEMA sizes 56C, 143TC, 145TC, 182C, 184C). The tough anodizedaluminum housing with thru-shaft design resists the vibration and hazards of anindustrial environment. In addition, a C-face gasket kit is included free for motorshaft protection and enclosure.
Open Collector Output WiringThe ZR series of sensors have open collector outputs. An open collector
output brings the uncommitted collector of the encoder switching device to theexternal world. Because the collector element is not associated with the sensorsupply voltage, the sensor output collector may be “pulled up” to externalvoltages different than the encoder supply voltage (40 VDC maximum). NPNopen collector outputs are current sinking devices. An output signal will not begenerated unless a pull-up resistor is connected from the open-collector to thepositive side of an external supply. The same supply can be used for poweringthe unit and for the pull-up resistor.

MOUNTING INSTRUCTIONSMounting Kit Items Included:
4 ea. - 3/8" 16 x 1.0" Length Socket Head Cap Screws,Black Alloy.
4 ea. - 3/8" High Collar Spring Lock washer, Steel Zinc.1 ea. 3/32" Hex Allen Wrench, Long arm.
Note: The ZR encoder can mount to many types of C face devices. Inthese mounting instructions, we will refer to the device as a motor.
Step 1After carefully unpacking the unit, inspect to insure the motor
shaft is the correct size and free of all burrs or aberrations. Slidethe ZR Encoder over the motor shaft. DO NOT USE EXCESSIVEFORCE: There is a rubber O-ring in the Encoder locking collarthat will provide a small amount of resistance as it engages theshaft. If the encoder does not slide easily See Note 1 below.
Step 2Install the four 3/8" 16 x 1.0" socket head cap screws with lock washers
through the holes in the Encoder C face and tighten securely to the motor.
Step 3Insure the shaft locking collar is flush with the Encoder cover plate. Prevent
the motor shaft from turning (See Note 2 for additional information) andtighten the four 4-40 Allen head cap screws in the locking collar evenly in acrossing pattern. See Figure 1. Make sure the screws are securely tightened andthe front of the locking collar remains flush with the encoder cover plate. If thecollar does not turn true when the motor shaft is rotated, loosen the four screwsand repeat the procedure.
In Case of Difficulty:Note 1: Make sure the four 4-40 Allen head cap screws in the front of the
Encoder locking collar are loose and the collar is not cocked or jammed.Clean the shaft of any burrs using fine crocus cloth. The O- ring in theEncoder locking collar may need a small amount of additional lubrication.
Note 2: When tightening the screws in the locking collar avoid holding themotor shaft with anything that may scar or burr the shaft.

MODELS ZPJ - LARGE THRU-BORE ROTARY PULSE GENERATOR
GENERAL DESCRIPTIONThe Model ZPJ ia a thru-bore encoder with a bore of 0.625" (15.875 mm).
Additional mounting kits are available to adapt it to both standard and metricshaft sizes. This unit is ideal for applications requiring a miniature, highprecision, low cost encoder, designed with all metal construction for years oftrouble-free operation.
The ZPJ encoder has a flexible arm mount and blind hollow shaft. It uses twoset screws that are 90° apart to clamp the encoder's hub to the motor shaft. TheNPN Open Collector outputs are each current limited to 20 mA. The outputs arestandard quadrature with index, and are available in resolutions up to 2500pulses per shaft revolution. The quadrature separation is typically 90 electricaldegrees. Output A leads output B for clockwise rotation of the encoder shaft.
Open Collector Output WiringThe ZPJ encoder has open collector outputs. An open collector output brings
the uncommitted collector of the encoder switching device to the externalworld. Because the collector element is not associated with the sensor supplyvoltage, the sensor output collector may be “pulled up” to external voltagesdifferent than the encoder supply voltage (40 VDC maximum). NPN opencollector outputs are current sinking devices. An output signal will not begenerated unless a pull-up resistor is connected from the open-collector to thepositive side of an external supply. The same supply can be used for poweringthe unit and for the pull-up resistor.

MODEL ZMD - MINIATURE LENGTH SENSOR(Replaces MODEL LSM)
DESCRIPTIONDesigned for light to medium duty sensing applications, the Miniature Length
Sensor, Model ZMD, is compact in size and easy-to-use. It features a built-in spring-loaded torsion arm that provides a simple-to-
adjust torsion load, allowing the unit to be mounted in almost any orientation,including upside down. Using a 6" or 200 mm wheel, the ZMD can be used onalmost any surface, while operating at speeds up to 3000 feet per minute. Thehousing is a durable, conductive composite material that will eliminate staticbuild up. Whether you need to measure speed, position, or distances, the ModelZMD is the ideal solution. For other pulse rates and/or wiring configurations,contact the factory for further details.
Open Collector Output WiringThe ZMD sensors have open collector outputs. An open collector output
brings the uncommitted collector of the encoder switching device to the externalworld. Because the collector element is not associated with the sensor supplyvoltage, the sensor output collector may be “pulled up” to external voltagesdifferent than the encoder supply voltage (40 VDC maximum). NPN opencollector outputs are current sinking devices. An output signal will not begenerated unless a pull-up resistor is connected from the open-collector to thepositive side of an external supply. The same supply can be used for poweringthe unit and for the pull-up resistor.

VARIOUS CABLE ASSEMBLIES AVAILABLE
MODEL ZLZ - LINEAR CABLE ENCODER(Replaces MODEL LES)
DESCRIPTIONThe Linear Cable Encoder can provide an accurate, yet low cost solution for
Linear Measurement applications. Common applications include robotics,extrusion presses, valve positioning, textile machinery, and gate controlpositioning, just to name a few. The ZLZ has some unique advantages overother sensing solutions. Using a stainless steel cable, perfect parallel alignmentis no longer required and with a 50 inch cable reach, it can easily be mountedaway from harsh environments. The ZLZ is available in a quadrature output,allowing the sensor to operate in positioning applications.
Additional cable exit configurations, pulses per inch, and mating connectorsare available on special request. Contact the factory for details.
Open Collector Output WiringThe ZLZ sensors have open collector outputs. An open collector output
brings the uncommitted collector of the encoder switching device to the externalworld. Because the collector element is not associated with the sensor supplyvoltage, the sensor output collector may be “pulled up” to external voltages (40VDC max.) different than the encoder supply voltage . NPN open collectoroutputs are current sinking devices. An output signal will not be generatedunless a pull-up resistor is connected from the open-collector to the positive sideof an external supply. The same supply can be used for powering the unit andfor the pull-up resistor.

ZDHDIMENSIONS In inches (mm)ZNH
Open Collector Output WiringThe ZDH and ZNH series of sensors have open collector outputs. An open
collector output brings the uncommitted collector of the encoder switchingdevice to the external world. Because the collector element is not associatedwith the sensor supply voltage, the sensor output collector may be “pulled up”to external voltages different than the encoder supply voltage (40 VDCmaximum). NPN open collector outputs are current sinking devices. An outputsignal will not be generated unless a pull-up resistor is connected from the open-collector to the positive side of an external supply. The same supply can be usedfor powering the unit and for the pull-up resistor.
REPLACEMENTNote: The RPGD connections are made by a 24 inch cable. The ZDH uses a 7-
Pin MS connector.

DESCRIPTIONThe units are rugged, incremental encoders that convert shaft rotation into a
current sinking pulse train.Internally, a single L.E.D. light source and a photologic sensor in conjunction
with a shaft-mounted, durable, metal-etched encoder disc, provides signalaccuracy and reliability to 50 KHz. The DC input power supply requirement isa versatile +8 to +28 VDC, and is reverse polarity protected. The NPN OpenCollector Transistor Output is current limited to 40 mA and is compatible withmost RLC counters, rate indicators, controllers and accessories.
All units are packaged in a rugged cast aluminum housing with a gasketed,rear aluminum cover. The 3/8" (9.53 mm) diameter heavy duty stainless steelshaft and sealed, lifetime-lubricated precision ball bearings are preloaded forminimum end play and rated for continuous use up to 6000 RPM. They aredesigned to meet NEMA 13/IP54 environmental requirements. All units aresupplied with 10 feet (3M) of PVC jacketed 3-wire, 22 AWG cable withstranded shield wire and 100% foil shield coverage.
MODEL ZCH - QUADRATURE OUTPUT ROTARY PULSE GENERATORMODEL ZFH and ZGH - QUADRATURE OUTPUT LENGTH SENSORS(Replaces MODELS RPGQ, LSQS and LSQD respectively)
ROTARY PULSE GENERATORThe ZCH can be direct-coupled to a machine shaft by means of a flexible
bellows, spring or rubber sleeve type coupler, etc., that allows for axial and radialmisalignment. They can also be coupled with instrument timing belts and pulleysor gears. The housing may be rigidly face-mounted with the 4, #8-32 threadedholes. The 3-wire shielded cable exits through a cord connector.
LENGTH SENSORThe length sensors are available in both Single Ended Shaft (ZFH) and
Double Ended Shaft (ZGH) versions, both of which include a Stainless SteelHandle Tube for mounting and 10 feet (3.05 M) of 3-wire shielded cable. Whenmounted to a Length Sensor Hinge Clamp Assembly (See Model LSAHC001)and coupled with one or two Measuring Wheels (See Measuring Wheels), a lowcost, versatile and highly accurate length measurement system can beconfigured.
LENGTH SENSOR MEASUREMENT ACCURACYFactors which affect measurement accuracy include Measuring Wheel
accuracy and wear, and material conditions. Ideally, materials which are hard,thin and strong provide good readings. Conversely, soft, thick and elasticmaterials can present problems in obtaining true readings. Count or RateIndicators with “input scaling” can compensate for Measuring Wheel wear andmaterial elasticity and compliance errors. In addition, English/Metricconversions may also be accomplished.
LENGTH SENSOR ACCESSORIESThe Length Sensor Hinge Clamp Assembly provides an easy method for
attachment & mounting the Length Sensors and LSCB1 Conversion Bracket.The removable top on the solid aluminum LSAHC mounting block allowsquick installation of the Length Sensor handle tube and provides secureclamping retention. The mounting block steel shaft pivots freely in oilimpregnated sintered bronze bushings, and aluminum right angle bracketsallow mounting the assembly via clearance holes for 1/4" (6.35 mm) dia. bolts(See LSAHC Dimensions & Mounting).
Open Collector Output WiringThe ZCH, ZFH, and ZGH series of sensors have open collector outputs. An
open collector output brings the uncommitted collector of the encoderswitching device to the external world. Because the collector element is notassociated with the sensor supply voltage, the sensor output collector may be“pulled up” to external voltages (40 VDC max.) different than the encodersupply voltage . NPN open collector outputs are current sinking devices. Anoutput signal will not be generated unless a pull-up resistor is connected fromthe open-collector to the positive side of an external supply. The same supplycan be used for powering the unit and for the pull-up resistor.

2. The number of lines on the optical disc determines the Pulses Per Revolution(PPR).
3. Duty Cycle is the relationship of output “High” time, “a”, to output “Low”time, “b”, and is expressed as a High/Low percentage ratio, ie....% High time= a/(a+b) x 100; % Low time = b/(a+b) x 100.
4. Quadrature Phase “c” is specified as the lead or lag between Channel A & Bin electrical degrees. Nominally 90° (1/4 cycle).
LENGTH SENSOR MOUNTING CONSIDERATION1. Length Sensors should be mounted so measuring wheel(s) contact ribbon,
strip or web as it passes over a roller. As an alternative, wheel(s) can be drivenby roller surface next to material being measured.
2. Note: The weight at the Length Sensor unit provides sufficient traction foraccurate operation when mounted, with arm angle from horizonal notexceeding ±30o.
3. Tension on signal cable can cause wheel(s) to lift. Make sure cable is clampedto machine frame near thev unit and allow slack.

with a shaft-mounted, durable, metal-etched encoder disc, provides signalaccuracy and reliability to 10 KHz. The DC input power supply requirement isa versatile +8 to +35 VDC, and is reverse polarity protected. The NPN OpenCollector Transistor Output is current limited to 40 mA and is compatible withmost RLC counters, rate indicators, controllers and accessories.
All units are packaged in a rugged cast aluminum housing with a gasketed,rear aluminum cover. The 3/8" (9.53 mm) diameter heavy duty stainless steelshaft and sealed, lifetime-lubricated precision ball bearings are preloaded forminimum end play and rated for continuous use up to 6000 RPM. The RPGCand LSCS are designed to meet NEMA 13/IP54 environmental requirements.All units are supplied with 10 feet (3M) of PVC jacketed 3-wire, 22 AWG cablewith stranded shield wire and 100% foil shield coverage. OperatingTemperature range is -18°C to +60°C.
MODEL RPGCThe RPGC can be direct-coupled to a machine shaft by means of a flexible
bellows, spring or rubber sleeve type coupler, etc., that allows for axial and radialmisalignment. They can also be coupled with instrument timing belts and pulleysor gears. The housing may be rigidly face-mounted with the 4, #8-32 threadedholes. The RPGC’s 3-wire shielded cable exits through a cord connector.
MODEL LSCThe LSC is available in both Single Ended Shaft (LSCS) and Double Ended
Shaft (LSCD) versions, both of which include a Stainless Steel Handle Tube formounting and 10 feet (3.05 M) of 3-wire shielded cable. When mounted to aLength Sensor Hinge Clamp Assembly (See Model LSAHC001) and coupledwith one or two Measuring Wheels (See Measuring Wheels), a low cost,versatile and highly accurate length measurement system can be configured.

RPGC ORDERING INFORMATION
LENGTH SENSOR MEASUREMENT ACCURACYFactors which affect measurement accuracy include Measuring Wheel
accuracy and wear, and material conditions. Ideally, materials which are hard,thin and strong provide good readings. Conversely, soft, thick and elasticmaterials can present problems in obtaining true readings. The great majority ofthese situations, where this effect is consistent, can be compensated for byapplying a multiplier to the output pulse train so as to obtain a correctedmeasurement. Count or Rate Indicators with “input scaling” can compensatefor Measuring Wheel wear and material elasticity and compliance errors. Inaddition, English/Metric conversions may also be accomplished (See RLCcatalog for more information).
* RPG’s and LSC’s with 120 and 200 PPR outputs employ an internal doublingcircuit and deliver a fixed 50 µsec ±20% output pulse at the leading and trailingedge of a passing slot. Additional doubling in external indicators or circuits maynot be applicable. These outputs derated to 7300 Hz due to internal x2 circuitry.

When the desired output of an RPG and wheel combination is either in feetor inch units, selection of the proper combination is relatively straight forward.For example, with a 1-foot wheel circumference, a 1 PPR Rotary PulseGenerator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1pulse/inch); 100 PPR would yield 100 pulses/ft; and 120 PPR would permitmeasuring to 1/10th of an inch (1/120th of a foot).
Measuring in yards or meters, however, is a bit more involved since a 1-yardor 1-meter circumference wheel would be prohibitively large. Instead, 4/10 yardand 4/10 meter wheels can be used in conjunction with RPGB.

GENERAL DESCRIPTIONThe RPGD is a heavy duty, extremely rugged, reliable, yet compact encoder
designed for harsh factory and plant floor environments. The RPGD conformsto NEMA 4, 13 and P66 standards. Typical applications include motion controlfeedback, machine control, process control, elevator controls, conveyors, textileequipment, robotics and food processing.
Open Collector Output WiringThe RPGD series of sensors have open collector outputs. An open collector
output brings the uncommitted collector of the encoder switching device to theexternal world. Because the collector element is not associated with the sensorsupply voltage, the sensor output collector may be “pulled up” to externalvoltages (40 VDC max.) different than the encoder supply voltage . NPN opencollector outputs are current sinking devices. An output signal will not begenerated unless a pull-up resistor is connected from the open-collector to thepositive side of an external supply. The same supply can be used for poweringthe unit and for the pull-up resistor.
SPECIFICATIONS1. SUPPLY VOLTAGE: 5 to 28 VDC, 100 mA max.2. OUTPUTS: Single channel or quadrature available (See Ordering
Information): NPN Open Collector Transistor, VOH = 40 VDC max.;100 mA max. current. For quadrature units, Channel A leads Channel B for

Open Collector Output WiringThe following sensors (RPGN and RPGO) have open collector outputs. An
open collector output brings the uncommitted collector of the encoderswitching device to the external world. Because the collector element is notassociated with the sensor supply voltage, the sensor output collector may be“pulled up” to external voltages different than the encoder supply voltage (40VDC maximum). NPN open collector outputs are current sinking devices. Theoutput signal can not be observed unless the circuit is completed externally.

Open Collector Output WiringThe following sensors (RPGN, RPGO, and RPGP) have open collector
outputs. An open collector output brings the uncommitted collector of theencoder switching device to the external world. Because the collector elementis not associated with the sensor supply voltage, the sensor output collector maybe “pulled up” to external voltages different than the encoder supply voltage (40VDC maximum). NPN open collector outputs are current sinking devices. Theoutput signal can not be observed unless the circuit is completed externally.

! 100, 200 & 500 PULSES PER REVOLUTION! QUADRATURE CURRENT SINKING OUTPUTS TO 50 KHz

! SEALED PRECISION BALL BEARINGS! RUGGED CAST ALUMINUM HOUSING! 3/8" DIA. STAINLESS STEEL SHAFT! WIDE INPUT SUPPLY VOLTAGE RANGE & LOW CURRENT
OPERATION! EXCEPTIONAL PRICE/PERFORMANCE
DESCRIPTIONThe RPGQ and LSQ are rugged, incremental encoders that convert shaft
rotation into two output signals that are in quadrature relationship to oneanother (see Fig.1). This output arrangement allows the direction of shaftmovement to be determined in applications requiring positioning, bi-directionalcounting or anti-backlash counting.
Internally, a single L.E.D. light source and a monolithic sensor array inconjunction with a shaft-mounted, durable, metal-etched, encoder disc,provides signal accuracy and reliability to 50 KHz. The DC input power supplyrequirement is a versatile +8 to +28 VDC, and is reverse polarity protected.The two NPN Open Collector Transistor Outputs are each current limited to 40mA and are compatible with all RLC quadrature input counters, controllers andaccessories.
All units are packaged in a rugged cast aluminum housing with a gasketed, rearaluminum cover. The 3/8" (9.5 mm) diameter heavy duty stainless steel shaft andsealed, lifetime-lubricated precision ball bearings are preloaded for minimum endplay and rated for continuous use up to 6000 RPM. RPGQ and LSQS meetNEMA 13/IP54 environmental requirements. All units are supplied with 10 feet(3.05 M) of PVC jacketed 4-wire, 22 AWG cable with stranded shield wire and100% foil shield coverage. Operating Temperature range is 0°C to +70°C.
MODEL RPGQThe RPGQ can be direct-coupled to a machine shaft by means of a flexible
bellows, spring or rubber sleeve type coupler, etc., that allows for axial andradial misalignment. They can also be coupled with instrument timing belts andpulleys or gears. The housing may be rigidly face-mounted with the 4, #8-32threaded holes. The RPGQ’s 4-wire shielded cable exits through a cordconnector.
MODEL LSQThe LSQ is available in both Single Ended Shaft (LSQS) and Double Ended
Shaft (LSQD) versions, both of which include a Stainless Steel Handle Tube formounting and 10 feet (3.05 M) of 4-wire shielded cable. When mounted to aLength Sensor Hinge Clamp Assembly (See Model LSAHC001) and coupledwith one or two Measuring Wheels (See Measuring Wheels), a low cost,versatile and highly accurate length measurement system can be configured.
LENGTH SENSOR MEASUREMENT ACCURACYFactors which affect measurement accuracy include Measuring Wheel
accuracy and wear, and material conditions. Ideally, materials that are hard,thin and strong provide good readings, conversely, soft, thick and elasticmaterials can present problems in obtaining true readings. The great majorityof these situations, where this effect is consistant, can be compensated for byapplying a multiplier to the quadrature output pulse train so as to obtain acorrected measurement. Counter or Rate Indicators with “input scaling” cancompensate for Measuring Wheel wear and material elastic and complianceerrors. In addition, English/Metric conversions may also be accomplished (SeeRLC catalog for more information).
RPGQ = 1.03 × 10-4 oz. - in. - sec.2 (7.30 × 10-4N - mm - sec2)LSQS = 1.03 × 10-4 oz. - in. - sec.2 (7.30 × 10-4N - mm - sec2)LSQD = 1.30 × 10-4 oz. - in. - sec.2 (9.21 × 10-4N - mm - sec2)
6. OPERATING TEMPERATURE: 0°C to +70°C (+32°F to +158°F)7. WEIGHT (LESS CABLE):
RPGQ = 14.3 oz. (406 g)LSQS = 22.0 oz. (623 g)LSQD = 22.7 oz. (643 g)
LENGTH SENSOR MOUNTING CONSIDERATION1. Length Sensors should be mounted so measuring wheel(s) contact ribbon,
strip or web as it passes over a roller. As an alternative, wheel(s) can bedriven by roller surface next to material being measured.
2. Note: The weight at the Length Sensor unit provides sufficient traction foraccurate operation when mounted, with arm angle from horizonal notexceeding ±30o.
3. Tension on signal cable can cause wheel(s) to lift. Make sure cable isclamped to machine frame near LSQ and allow slack.

NOTES:1. Channel A leads Channel B for clockwise shaft rotation when viewed from
housing front. Conversely, Channel B leads Channel A for Counterclockwiseshaft rotation.
2. The number of lines on the optical disc determines the Pulses Per Revolution(PPR).
3. Duty Cycle is the relationship of output “High” time, “a”, to output “Low”time, “b”, and is expressed as a High/Low percentage ratio, ie....% Hightime = a/(a+b) x 100; % Low time = b/(a+b) x 100.
4. Quadrature Phase “c” is specified as the lead or lag between Channel A & Bin electrical degrees. Nominally 90° (1/4 cycle).
LENGTH SENSOR ACCESSORIESModel LSAHC - Length Sensor Hinge Clamp Assembly. The Length Sensor
Hinge Clamp Assembly provides an easy method for attachment & mountingof Model LSC and LSQ Length Sensors and LSCB1 Conversion Bracket. Theremovable top on the solid aluminum LSAHC mounting block allows quickinstallation of the Length Sensor handle tube and provides secure clampingretention. The mounting block steel shaft pivots freely in oil impregnatedsintered bronze bushings, and aluminum right angle brackets allow mountingthe assembly via clearance holes for 1/4" (6.35 mm) dia. bolts (See LSAHCDimensions & Mounting).
When the desired output of an RPG and wheel combination is either in feetor inch units, selection of the proper combination is relatively straight forward.For example, with a 1-foot wheel circumference, a 1 PPR Rotary PulseGenerator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1pulse/inch); 100 PPR would yield 100 pulses/ft; and 120 PPR would permitmeasuring to 1/10th of an inch (1/120th of a foot).
Measuring in yards or meters, however, is a bit more involved since a 1-yardor 1-meter circumference wheel would be prohibitively large. Instead, 4/10 yardand 4/10 meter wheels can be used in conjunction with RPGB.

Bulletin No. RPGB/H-N
Drawing No. LP0202
Released 4/03
RPG’s contain an L.E.D. light source and a photo sensor that scans a shaft-mounted, slotted disc. An internal pulse-shaping amplifier circuit delivers arectangular pulse signal from the current sinking output in response to thepassing slots as it rotates. RPG’s can be direct-coupled to a machine shaft bymeans of a flexible-bellows, spring, or rubber sleeve type coupling that allows
for axial and radial misalignment. They can also be coupled with lightinstrument timing-belts. Timing-belt drives also allow convenient gear-up orgear-down speed ratio changes that can be useful for obtaining non-standardPPR rates.
* Only Stock PPR’s listed, other PPR’s as well as Quad. (Type “1”) outputavailable on special order.
ABOUT QUADRATURE OUTPUTA quadrature output consists of two pulse trains, one of which is 90°
(electrical) out of phase with the other. By virtue of this arrangement thedirection of motion can be determined. Referring to the following waveform,when the CNT output (Pin C) goes from low to high while the Quadratureoutput (Pin D) is low, the motion is counter-clockwise.

DESCRIPTIONThis conversion bracket allows the customer to assemble a custom length
sensor by purchasing the following items separately.1. Length Sensor Conversion Bracket (P/N LSCB1000)2. RPGB with appropriate PPR and Single Channel or Quadrature Output.3. One or two measuring wheels. Install OF & OK measuring wheels with setscrew hub facing RPGB shaft (as shown). Apply thread locking material towheel set screw threads during installation to RPGB shaft.4. Hinge Clamp Assembly (P/N LSAHC001)Note: To complete installation, insure guards, shields or other devices are inplace to protect personnel from rotating equipment.
The tubular arm length of this bracket, related to the wheel axis center-line ofthe RPGB is 6.8" similar to the LSQ. The 10´ long, 4-wire, shielded cable(included with conversion bracket) has the same color coding as described forthe RPGB cable P/N CCARPG01. Screws for mounting the conversion bracketto the RPGB are included.

The Length Sensor Hinge Clamp Assembly provides an easy methodfor attachment and mounting of Model LSC and LSQ Length Sensors andLSCB1 Conversion Bracket. The removable top on the solid zinc LSAHCmounting block allows quick installation of the Length Sensor handle tubeand provides secure clamping retention. The mounting block pivots freelyin zinc right angle brackets to allow mounting the assembly via clearanceholes for 1/4" dia. bolts.
The lock washers must be used as indicated (between the bolt head andthe top clamp piece). Assemble the top clamp piece as follows.
1. Tighten both bolts so that the top clamp half draws down evenly onthe sensor tube.
2. Tighten the bolts until both lock washers are flat.3. Then turn each bolt an additional ½ to ¾ turn.
