Description
The OPB712 consists of an infrared emitting diode and an NPN silicon photodarlington mounted “side-by-side” on parallel axes in a infrared transmissive plastic housing. Both the emitting diode and photodarlington are molded out of black infrared transmissive plastic to reduce ambient light noise. The photodarlington responds to radiation from the emitter only when a reflective object passes within its field of view.

FEATUREs
● Photodarlington output
● Unfocused for sensing diffuse surface
● Low cost plastic housing
