    Products Detail

    Each reflective object sensor consists of an infrared emitting diode and a NPN silicon phototransistor or photodarlington output. The OPB747WZ and OPB748WZ feature a red visible LED for better contrast when detecting black marks on white surfaces. All devices 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 various lens options including no windows, blue polysulfone windows for dust protection, or opaque aperture windows with offset openings for improved target resolution. These sensors respond to radiation only when a reflective object passes 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, offset windows), Non-contact reflective object sensor, Red visible LED option for better contrast on white surfaces

    • Assembly line automation
    • Machine automation
    • Machine safety
    • End of travel sensor
    • Door sensor
    • Thermal Paper Mark
