Choice of Phototransistor (OPB706) or Photodarlington (OPB707) output
Unfocused for sensing diffuse surface Low cost plastic housing Designed for use with PCBoards or connectors
The OPB706 consists of an infrared Light Emitting Diode (LED) and an NPN silicon Phototransistor mounted “side-by-side” on parallel axes in a black plastic housing. The OPB707 consists of an infrared LED and an NPN silicon Photodarlington mounted “side-by-side” on parallel axes in a black plastic housing.
On both OPB706 and OPB707, the LED and Phototransistor / Photodarlington are molded using dark infrared transmissive plastic to reduce ambient light noise. The Phototransistor / Photodarlington responds to light from the emitter when a reflective object passes within its field of view of the device.
