When there’s no spacefor a photoelectric sensor,there is only one solution:user fiber optics!
If there are no particulardemands for ruggedness,ambient temperature orchemical resistance, thenplastic fiber optics are theright choice.
A wide range of specialbase units with variousperformance and functionfeatures is available forusing the fiber optics. Fromthe simple version withpotentiometer to the high-end unit with display.
Applications
– Small parts detection– Suitable for tight mounting
conditions– Inspecting parts features– Counting tasks
(e.g. counting drops)– Precise parts positioning– Handling and assembly– Robotics
For standard applications,choose the BOS 15K. Itsmain features are cost-effectiveness and ease ofhandling.
Features
– Sensitivity setting with a270° potentiometer
– Contamination indicator– PNP/NPN wiring
(cable version)

The BOS 20K isprogrammed using teach-inor manually with buttons. Itcombines automatic settingwith the simple press of abutton for using additionalfunctions (e.g., time delay) asneeded.2 sensitivity levels aredirectly available, which canbe changed as needed using2 buttons. A control line canbe also used to teach thesensor remotely.

The BOS 73K withindicators simplifiesoperation of the sensor andgives an accurate overviewof the settings. The displayshows sensitivity, signalstrength as well as ancillaryfunctions. The switchingpoint and hysteresis can beautomatically acquired butalso manually set. Thepowerful red light emitterpermits very long sensingand detection ranges.Both a switching and alarmoutput are provided. Timefunctions can also be set.Two transmission channelsare provided for using mul-tiple sensors without mutualinterference.

There are basically two typesof fiber optics: diffuse orthrough-beam.The diffuse models have anintegrated emitter andreceiver at the cable end.The through-beams use twoseparate cables.

Another plus
For the ultimate in flexibility,fiber optics for userassembly are also available:any desired combinationsare possible with the trim-to-length duplex cable andvarious end fittings.
It’s easy to see why fiberoptics are so commonlyused: The variety of endconfigurations, with straightor angled light exit, flexibleoptical head or coaxialfibers, the various fiberdiameters and the ability totrim them to the desiredlength.
Applications
– Small parts detection– For tight mounting
conditions– Inspecting parts features– Counting (e.g. counting
drops)– Precise parts positioning– Handling and assembly– Robotics
If “off-the-rack” solutionsaren’t for you, we have thealternative: Trim fiber opticcables to the length yourequire from a 20 m roll. Youwill only use exactly as muchcable as needed – providingsavings especially if you areusing multiple sensors.For simple applications, forexample, you may not needan end piece; simply clampthe end. Or for convenienceand flexibility, select fromamong the available endpieces. The plastic fiberoptic cable is simply crimpedinto the end piece. No gluingis necessary, and the endpiece can be removed at anytime.

Series BFO 18A glass fiberoptic cables are designed forseries BOS 18M tubularsensors and are usedwherever a high level offunction reserve or chemicalresistance is required.Extremely temperatures arealso no problem.
Various straight or right-angle versions are availablewith polyurethane jacket,corrugated metal armor orsilicon protective jacket.

Ranges referenced to Kodak gray card 90 % reflective.
Diffuse with glass fiber optics used as retroreflective:Ranges are referenced to BOS R1 reflector.
When using as a retroreflective type, twice the switching distancemust be used as the object dead zone.
Please append the desired length L of the fiber optics cableto the ordering code.Increments from 0.5 m to max. 3 m possible.Example:BFO 18...-30-0.5 for 0.5 m fiber lengthBFO 18...-30-2 for 2 m fiber length

Note!A through-beam fiber optic cable changes the normally open signal of the base unitinto a normally closed signal!
