OPB973T51 [Optek]

Non-contact Photologic slotted optical switches built in 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. The opaque plastic housing minimizes sensitivity to visible and near-infrared external light. Aperture width choices provide different optical resolution for motion sensing. Covered apertures offer dust protection, while open apertures provide maximum protection against external light. Electrical operation is over a wide supply voltage range with near-infrared LED emissions (850–940nm). Detector digital output logic choices include buffer or inverter with totem-pole or open-collector driver circuits for simplified interface to various electrical requirements. Custom electrical, wire, and cabling services are available.
