OPB707A [Optek]

The OPB706 and OPB707 are reflective optical sensors consisting of an infrared LED and an NPN silicon phototransistor or photodarlington output mounted side-by-side on parallel axes. They use dark infrared transmissive plastic to reduce ambient light noise and respond to light from the emitter when a reflective object passes within its field of view. Designed for use with PC boards or connectors, these low-cost sensors feature unfocused detection for diffuse surfaces and offer custom electrical, wire, and cabling options.
