Proximity Sensors Selection
All applications have certain specificneeds, but, in general, the following stepswill help you choose the correct sensor foryour application:
Step 1:What is the sensing distance required?
The sensing distance is the distancebetween the tip of the sensor and theobject to be sensed. The selection guideand the specifications table for eachsensor family lists the sensing distances.
Some things to keep in mind are:
A. In many applications, it is beneficial toplace the sensor as far as possible from thesensing object due to temperatureconcerns. If a sensor is placed too close toa hot temperature source, the sensor willfail quicker and require more maintenance.
Greater distance may be achieved withextended and triple range sensors. Inmany applications, a sensor may not bemountable close to the sensed object. Inthis case, longer sensing distances areneeded. The Centsable product lineoffers extended sensing distance sensorsfrom 8mm to 30mm, and triple sensingdistance sensors in 8mm and 12mmround formats.
In many cases, using an extended distancesensor to get the sensor farther away fromthe detected object can be beneficial tothe life of the sensor. For example,without an extended distance sensor youmay not be able to place the sensor closeenough to the detectable object, or youmay need to buy more expensive hightemperature sensors.
Another example would be a mechanicalovershoot situation, where mounting thesensor farther from the detection objectmay eliminate unneeded contact with thesensor, thereby extending the life of thesensor.
These are just a few examples, but thebenefits of using extended distancesensors are obvious in many applications.Think of how extended distance sensorscould save you time and money in yourapplication.
B. The material being sensed (i.e. brass,copper, aluminum, steel, etc.) makes adifference in the type of sensor needed.
Note: If you are sensing a non-metallicobject, you must use a capacitive sensor.
The sensing distances specified in thisdesk reference were calculated usingFE360 material. Many materials are moredifficult to sense and require a shorterdistance from the sensor tip to the objectsensed.
If sensing a material that is difficult tosense, you may consider using our uniquestainless steel sensing technology. Thiswill measure virtually all materials at thespecified sensing distances.
Step 2:How much space is available formounting the sensor?
Have you ever tried using a round sensoror short body versions, and not been ableto make it fit? Our rectangular sensorscan meet your needs. The same tech-nology used in a standard round prox-imity sensor is enclosed in a rectangularhousing. This technology includessensing distances, electrical protectionand switching frequencies similar toround sensors.
Step 3:Is a shielded or unshielded sensorneeded?
Shielded and unshielded sensors are alsoreferred to as embeddable and non-embeddable. Unshielded sensors allowlonger sensing distances but shieldedsensors allow flush mounting.
Step 4:Consider environmental placementconcerns. Will the sensor be placedunderwater, in a high-temperature envi-ronment, continually splashed with oil,etc.? This will determine the type ofsensor you may use. In the selection tableand in the specification tables for eachsensor family, we list the environmentalprotection degree ratings. Most of oursensors are rated IEC-IP67 and others arerated IP65 or IP68.
These ratings are defined as:
IP65: Protection from live or movingparts, dust, and protection from water jetsfrom any direction.
IP67: Protection from live or movingparts, dust, and protection from immer-sion in water.
IP68: Protection from live or movingparts, dust, and protection from submer-sion in water under pressure.

Step 5:What is the sensor output connected to?
Note: If using AC sensors, please skip thisstep.
The type of output required must bedetermined (i.e., NPN, PNP or analog).Most PLC products will accept eitheroutput. If connecting to a solid staterelay, a PNP output is needed.
Step 6a:Do I need 2, 3, or 4-wire discreteoutputs?
This is somewhat determined by what thesensor will be connected to. Some simpleguidelines to use are:
Step 6b:Do I need analog outputs?
This is determined by the sensor applica-tion and what the sensor will beconnected to. Devices with analogoutputs produce an analog output signalapproximately proportional to the targetdistance.
Step 7:Determine output connection type.
Do you want an axial cable factoryattached to the sensor (pigtail) or a quick-disconnect cable?
There are many advantages to using aquick-disconnect cable, such as easiermaintenance and replacement. All prox-imity sensors will fail in time and using aQ/D (quick disconnect) cable allows forsimple replacement.
Factory attached axial cables come in apre-determined 2m length. CD08/CD12Q/D cables come in 2m, 5m, and 7mlengths. Extension cables are available in1m and 3m lengths to extend the lengthof the standard Q/D cables.
Q/D cables are offered in PVC and PURjackets for meeting the requirements ofall applications. Axial cables typicallycome with a PVC jacket. PVC is a generalpurpose insulation while PUR providesexcellent oxidation, oil and ozone resis-tance. PUR is beneficial if the cable isexposed to oils or placed in directsunlight.
There are also advantages to a factoryattached axial cable:
Cost: The cable is integrated into thesensor and included in the price. Q/Dcables must be purchased separately.
Environmental impact: Since the cable issealed into the sensor, there is less chanceof oil, water or dust penetration into thesensor, which could cause failure.
HOW DO I CHOOSE THE RIGHT SENSOR?
Type Guidelines
2-wire• Will work with sinking or sourcing . . .
devices.• Only 2 wires to terminate.• Higher leakage current.
3-wire• Most popular output. Familiar to most
users. (Must select between NPN andPNP outputs.)
4-wire• Allows configurability in one device. .
May have both NPN/PNP selection or NO/NC selection. Allows user to stock one part for numerous applications.

The following descriptions refer to theEuropean standard EN 60947-5-2. ofSept. 95.
The specifications given here areintended to be minimum performancevalues described by the standard.
AlignmentProximity switches must not be mutuallyinfluenced. For this reason, a minimumdistance between them (referred to asalignment) must be provided.
Break function (N.C.,normally closed)A break function causes load current toflow only when a target is not detected.
Degree of protectionIf not otherwise specified, proximityswitches (when installed in accordancewith manufacturer’s instructions) haveminimum IP65 protection against dustand water jets.
Differential travel (H)The differential travel is given as a percentage of the effective operatingdistance (Sr) and is the maximum differ-ence between the switching distances.The differential is intentionally introduced to guarantee the stability ofthe output state in case the target is posi-tioned near the switching points.
Distance/target size graphIndicates the ON switching distancewhen target material and size changes.
Below are some typical values fordifferent target material of standarddimension:
Inox steel: 0.6-1 x Sn
Brass: 0.35-0.50 x Sn
Aluminum: 0.35-0.50 x Sn
Copper: 0.25-0.45 x Sn
Detection area graphThis is a graph of the parallel displace-ment needed to switch on (switch off,dashed line) as a function of the targetdistance. The construction of the curve isobtained by measuring the lateraldistance between the sensor axis and theedge of the target necessary to switch onor off at any target distance (see figurebelow.)
Electrical connectionsKeep sensor cables and power cablesseparated to avoid electrical interference.
The power supply voltage must notexceed the specified limits UB.
If a non-stabilized supply voltage is usedfor DC sensors, the maximum voltagepeak under minimum power consump-tion conditions and minimum voltagepeak under maximum power consump-tion must not exceed UB limits.
If the power supply of the sensor is alsoused to switch inductive loads, a suppres-sion device must be provided. A fuse toprotect the power supply line is alsorecommended.
Installation notesSelect a sensor compatible with the oper-ating environment: verify the compati-bility between building materials, thepresence of chemicals, temperaturerange, protection degree, vibrations,shocks, EMC, supply voltage available,load type, etc.
Select the sensor by referring to the sizeand type of material to be detected.
Check the minimum distances betweensensor and damping materials or anothersensor.
Never use this desk reference for instal-lation or operation of equipment. Referto manual for installation and opera-tion instructions.

Installation notes,(cont.)Check that the number of operationsdoes not exceed the maximum switchingfrequency. If the phase of the outputsignal is important, check the turn onand turn off time.
Metallic chips or dust must not accumu-late on the sensing face. The distancebetween the sensor and the object todetect must not exceed the assured oper-ating distance Sa; the best operatingdistance is Sn/2.
Check the effect of vibrations.
Install the sensor using the installationaccessories and do not exceed themaximum tightening torque.
Leakage currentThe leakage current is the current whichpasses through the output transistorwhen it is blocked (this must be takeninto account, especially in the case ofparallel connection of several switches).
LED status indicatorsProximity switches may incorporate oneor more color indicators. The meaning ofthe colors are:
CONTINUOUS GREEN: Power ONCONTINUOUS YELLOW: Output ONCONTINUOUS RED: Fault (on AC models, RED = output ON
Make function (N.O.,normally open)A make function causes load current toflow only when a target is detected.
Material influenceThe nominal sensing distance S(n) isdefined using precisely definedmeasuring conditions (See OperatingDistance.) Other conditions may resultin a reduction of the operating distance.The tables in the next column show theinfluence different target materials haveon the operating distances of the sensors.
MountingShielded (embeddable) proximity switches
These proximity switches may be flushmounted regardless of the metal beingused. For reliable operation, it is neces-sary to observe the minimum distancesfrom adjacent metal targets.
Unshielded (non-embeddable) proximity switches
When mounting non-embeddablemounting proximity switches inconducting materials (metals), it is neces-sary to observe the minimum distancesfrom adjacent metal targets. Flushmounting in non-conducting materials ispermitted.
Off-state (leakage)current (Ir)This is the current that flows through theload circuit of the proximity switch inthe OFF state at the maximum supplyvoltage.
Open collectorThe output transistor in not internallyconnected to a pull-up or pull-down load.It is therefore possible to connect anexternal load supplied by an externalvoltage.
Operating distance (sensing range) (S)The operating distance is the distance atwhich a standard target approaching theactive face of the sensor causes a sensoroutput state change.
Output type and loadconnections –3-wireNPNThere are two power wires and oneoutput wire. The switching element isconnected between the output wire andthe negative terminal, and the load isconnected between the output wire andthe positive terminal. In the ON state,the current sinks from the load into theswitching element.

Proximity Sensors Frequently Asked Questions
1 - 8 0 0 - 6 3 3 - 0 4 0 5Sensors17–56
How do inductive proximity switches work?
Inductive proximity switches are used todetect the presence of metallic objectswithout actually contacting the object.Their high-speed switching and smallsize make them indispensable in automa-tion applications.
Inductive proximity switches consist of acoil driven by an oscillator. The oscillatorcreates an electromagnetic field whichappears at the active face of the switch. Ifa metal target enters this area, the elec-tromagnetic field is reduced and theswitch turns on or off.
Some typical inductive sensor applica-tions are: counting metallic objects,monitoring the position of elements in amachine, sensing the presence of metallicparts like screws, etc., and measuring therotational speed of axial detecting cams.
What is the difference betweeninductive and capacitive sensors?
The primary difference is sensing mate-rial. Inductive sensors only detectmetallic objects while capacitive sensorswill detect materials such as wood, paper,liquids, cardboard, etc.
How do I know what size proximitysensor I need?
It depends on two factors: mountingspace and sensing distance. Each applica-tion has a specific space available for thesensor and each application has a require-ment for how close the sensor can bemounted to the sensed object.
What is the difference betweenshielded and unshielded?
With a shielded proximity sensor, theface of the sensor may be mounted flushwith metal whereas an unshielded sensormay NOT be mounted flush with metal(otherwise the sensor will always beON). In many applications, flushmounting is a requirement. Also,unshielded proximity sensors allow forgreater sensing distances.
What output do I need? NPN orPNP?
This is determined by the device you areconnecting the sensor to. MostDirectLOGIC PLC modules (except 305series) allow NPN or PNP sensors to beconnected. This is determined by howthe sensor is wired to the PLC.
How do I choose between normallyopen (N.O.) and normally closed(N.C.)?
N.O. sensors do not pass power to thePLC until an object is detected. N.C.sensors always pass power to the PLCuntil an object is detected. The majorityof Centsable sensors are N.O.; however,some sensors offer the option of N.C.,such as PKW, PMW and CT1 series.
When do I want quick disconnects(Q/D) versus embedded cable output?
There is a slight cost increase to purchasea sensor and a Q/D cable compared toonly purchasing a sensor with a pre-attached cable. However, the Q/Doutput allows easy replacement of a failedsensor. This is important in minimizingmachine or operation downtime.
What is the difference between 2-wire, 3-wire, and 4-wire sensors?
2-wire sensors: allows either NPN orPNP outputs (don't have to select).
3-wire sensors: standard sensors. Whenordering, you must choose betweenNPN and PNP output.
4-wire sensors: Allow either N.O. orN.C. outputs (don't have to select).Must still select NPN or PNP output.
Do Centsable sensors operate onAC or DC voltage?
The majority of Centsable sensorsoperate on 10-30 VDC. However, we dooffer the VT1, VK1, and VM1 series thatoperate on 20-253VAC.
Can my sensor be installed in awashdown area?
Yes. All Centsable proximity sensorscarry an IP67 or IP68 enclosure rating.This rating allows temporary submersionof the sensor into water.
What does switching frequencymean to my application?
This is how fast your sensor can sense anobject, reset, and sense another object.For example, if a sensor has a switchingfrequency of 100Hz or 100 cycles persecond, the sensor can sense a maximumof 100 objects per second. This is verycritical in many applications such as gearrotation measurement.
Can the sensor be put into avibrating environment?
Yes. Frequency range of 10-55 Hz,maximum amplitude of 1mm. Durationin any axis a maximum of 30 minutes.
What is the temperature range ofthe sensors?
Most sensors operate between -25° and70° F. However, check the specificationsfor exact ranges.
If I wire my proximity sensorwrong, will it damage it?
Possibly. All sensors contain polarityreversal, short-circuit and transient noiseprotection. However, the transientprotection is only effective under30VDC.

Notes:Centsable DC sensors operate on 10-30 VDC. If you are using a higher DC voltage with a competitor’s sensor, do not cross to Centsable. Comparable sensor overall lengths and thread lengths may vary slightly. Centsable AC sensors are VAC only. Some competitors’ sensors are AC/DC. Significant sensing distance (SD) differences are noted. Others may vary slightly. SS after the part number denotes the sensor is Stainless Steel. NPB after the part number denotes the sensor is Nickel Plated Brass. N.O. after the part number denotes the sensor operates normally open only. VDC after part number means to cross to Centsable only if competitor’s sensor is used in VDC application.
