    Products Detail

    OPB608 series reflective switches combine an infrared emitter (LED or VCSEL) with an NPN silicon phototransistor in a low-cost plastic housing. They feature phototransistor output, unfocused sensing for diffuse surfaces, enhanced signal-to-noise ratio, and reduced ambient light sensitivity. The devices are encapsulated in visible filtering epoxy (except OPB608R) and respond to radiation only when reflective objects pass within their field of view. Models include OPB608A/B/C (890nm LED, 0.050"-0.375" range), OPB608V (850nm VCSEL, 0.050"-1.200" range), and OPB608R (650nm visible red LED, 0.050"-0.300" range).

    Key Features

    • Phototransistor output, Unfocused for sensing diffuse surface, Low cost plastic housing, Enhanced signal to noise ratio, Reduced ambient light sensitivity
