    Category:

    Optical Sensors

    Manufacturer:

    Optek

    Description:

    Each reflective object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through OPB746WZ series consists of an infrared emitting diode and a NPN silicon phototransistor or a photodarlington. All these devices are mounted side-by-side on converging optical axes in a black plastic housing focusing on a small area and depth of field.

    Products Detail

    Non-contact reflective object sensors with focused maximum sensitivity. Available with phototransistor or photodarlington output. Features include various lens options (no windows, blue polysulfone windows for dust protection, or opaque aperture windows with offset openings for improved target resolution). The photosensor responds to radiation only when a reflective object passes within its field of view. Custom IC(ON) current binning, special wire lengths and connectorization available. OPB747WZ and OPB748WZ use a Red visible LED for better contrast when detecting black marks on white surfaces.

    Key Features

    • Focused for maximum sensitivity
    • Phototransistor or photodarlington output
    • Crosstalk does not exceed specified ICEO
    • 24" (610 mm) wire length (WZ series)
    • 26 AWG wire size (WZ series)
    • Various lens options
    • Non-contact reflective object sensor
    • Custom IC(ON) current binning available

    Application scenarios
