    Products Detail

    These reflective object sensors consist of an infrared emitting diode and a NPN silicon phototransistor or photodarlington (or red LED with low light level rejection phototransistor for OPB747WZ/OPB748WZ). Mounted side-by-side in black plastic housing with converging optical axes for focused detection. WZ series features wire leads and offers lens options including no windows, blue polysulfone windows, or opaque aperture windows with offset openings. Sensors respond to radiation only when reflective objects pass within their field of view.

    Key Features

    • Focused for maximum sensitivity
    • Phototransistor or photodarlington output
    • Crosstalk does not exceed specified ICEO
    • 24" (610 mm) wire length
    • 26 AWG wire size (WZ series)
    • Various lens options: no windows, blue polysulfone windows for dust protection, opaque aperture windows with offset openings for improved target resolution

    Application scenarios

    • Assembly line automation
    • machine automation
    • machine safety
    • end of travel sensor
    • door sensor
    • thermal paper mark detection
