 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. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
