TT Electronics - Optek Technology OPB730 Reflective Object Sensor

The OPB730 series Reflective Object Sensor features a gallium arsenide infrared emitting diode and an NPN silicon phototransistor positioned side-by-side on parallel axes. Each sensor is encased in a black plastic sleeve filled with transparent epoxy, with the OPB730F variant incorporating a filter material into the epoxy to minimize ambient light interference. An internal barrier prevents direct infrared emission from reaching the detector. This sensor offers a photodarlington output and is unfocused, optimized for detecting diffuse surfaces. It is suitable for various applications such as sensing and instrumentation, automation and process control, safety systems, and industrial environments.
