    Products Detail

    The series offers a standard housing with a 0.125" (3.18mm) wide slot. Users can specify output logic state, output driver circuit, aperture width, aperture surface, and mounting tab locations. Options include wire or PCB leads for electrical interface flexibility. 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. LED emissions are near-infrared (850-940nm). Custom electrical, wire and cabling services are available. Compliant to EU RoHS Directive 2002/95/EC.

    Key Features

    • 0.125" (3.175 mm) slot width
    • Choice of aperture (0.050" or 0.010" width)
    • Choice of opaque or IR transmissive shell material
