    Products Detail

    Slotted optical switches with a standard 0.125” (3.175 mm) slot width, offering choices of aperture width (0.050” or 0.010”), shell material (opaque or IR transmissive), mounting configurations, and lead spacing or wires. The device body is opaque plastic to minimize sensitivity to external light. Aperture width choices provide different optical resolution for motion sensing. Covered apertures provide dust protection, while open apertures provide maximum protection against external light. Available with phototransistor or photodiode (OPB355) detectors. LED emissions are near-infrared (850-940nm). Custom electrical, wire and cabling services are available. Compliant to EU RoHS.
