OPB711

Overview
 Choice of phototransistor or photodarlington output  Unfocused for sensing diffuse surface  Low-cost plastic housing  Choice of filter or unfiltered 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.
OPB711’s, 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...
