OPB712 TT Electronics

Reflective Object Sensor OPB711, OPB712 Features: Choice of phototransistor or photodarlington output Unfocused for sensing diffuse surface Product Photo Here Low-cost plastic housing Choice of filter or unfiltered Description: OPB711 consists of an infrared emitting diode and an NPN silicon phototransistor, mounted side-by-side on parallel axes in a black opaque plastic housing. The OPB712 consists of an infrared emitting diode and an NPN silicon photodarlington, mounted side-by-side on parallel axes in a black plastic housing. OPB711s, emitting diode and phototransistor are encapsulated in a filtering epoxy to reduce ambient light noise. Its phototransistor responds to radiation from the emitter only when a reflective object passes within its field of view. OPB712s emitting diode and photodarlington are encapsulated in a filtering epoxy to reduce ambient light noise.
