The OPB960/ 970/ 980/ 990 series of non-contact Photologic® sloꢀed opꢁcal switches provides flexibility in meeꢁng
applicaꢁon specific requirements for the design engineer.
Building from a standard housing with a 0.125” (3.18mm) wide slot, the user can specify output logic state, output driver
circuit, aperture width, aperture surface and mounꢁng tab locaꢁons. Furthermore, an opꢁon of wire or PCB leads allows
electrical interface flexibility.
The device body is an opaque plasꢁc which minimizes sensiꢁvity to both visible and near-infrared external light sources
which may impact operaꢁon. Aperture width choices provide different opꢁcal resoluꢁon for moꢁon sensing. A covered
aperture provides dust protecꢁon, while an open aperture provides maximum protecꢁon against external light sources.
Electrical operaꢁon is over a wide supply voltage range. LED emissions are near-infrared (850—940nm).
Detector digital output logic choices of buffer or inverter with totem-pole or open-collector driver circuit simplify interface
for various electrical requirements.
Custom electrical, wire and cabling services are available.
