OPB355T [Optek]

The slotted optical sensors in this series provide the flexibility of a custom device from a standard product line. 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 mounting tab locations. Furthermore, an option of wire or PCB leads allows electrical interface flexibility. The device body is an opaque plastic which minimizes sensitivity to both visible and near-infrared external light sources. Aperture width choices provide different optical resolution for motion sensing. A covered aperture provides dust protection, while an open aperture provides maximum protection against external light sources. Phototransistor sensor devices include OPB360, OPB370, OPB380, OPB390, OPB859, OPB860, OPB870, OPB880, OPB890. The OPB355 provides a photodiode detector with lower linear output-versus-light. Wide electrical output current ranges are available. LED emissions are near-infrared (850-940nm).
