Products Detail

Slotted optical sensors with a standard 0.125" (3.18mm) wide slot, offering customizable output logic state, output driver circuit, aperture width, aperture surface, and mounting tab locations. The device body is opaque plastic to minimize sensitivity to visible and near-infrared external light. Aperture width choices (0.050" or 0.010") provide different optical resolution for motion sensing. Covered apertures provide dust protection, while open apertures provide maximum protection against external light sources. The series includes phototransistor sensor devices (OPB360, OPB370, OPB380, OPB390, OPB859, OPB860, OPB870, OPB880, OPB890) and a photodiode detector (OPB355). Wide electrical output current ranges are available. LED emissions are near-infrared (850-940nm). Custom electrical, wire and cabling services are available. Compliant to EU RoHS Directive 2002/95/EC.
