    Products Detail

    The OPB852 and OPB853 series are slotted optical switches with an infrared emitter and a phototransistor (OPB852) or photodarlington (OPB853) sensor. They feature an inexpensive opaque plastic housing, a 0.125” (3.18 mm) slot width, and 0.290” (7.37 mm) lead spacing. The emitter and sensor have molded-in apertures (0.050” x 0.050” for emitter, 0.010” x 0.050” for sensor) for high resolution. Switching occurs when an opaque object passes through the slot.

    Key Features

    • Inexpensive opaque plastic housing
    • Choice of transistor (OPB852) or photodarlington (OPB853) output
    • Slot width: 0.125” (3.18 mm)
    • Lead spacing: 0.290” (7.37 mm)
    • Apertured for high resolution
