    Products Detail

    Each reflective object sensor consists of an infrared emitting diode (or red LED for OPB747WZ/OPB748WZ) and a NPN silicon phototransistor or photodarlington. The sensors are mounted side-by-side on converging optical axes in a black plastic housing focusing on a small area and depth of field. The WZ series offers wired devices with various lens options including no windows, blue polysulfone windows for dust protection, or opaque aperture windows with offset openings for improved target resolution. These devices respond to radiation only when a reflective object passes within its field of view.

    Key Features

    • Focused for maximum sensitivity, Phototransistor or photodarlington output, Crosstalk does not exceed specified ICEO, 24 inch wire length (WZ series), 26 AWG wire size, Various lens options (no windows, blue polysulfone, offset windows), Non-contact reflective object sensor

    Application scenarios

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