Product Summary

The OPB742 is a reflecctive object sensor. The OPB742 consists of an infrared emitting diode and an NPN silicon phototransistor mounted side by side on converging optical axes in a black plastic housing. Various options of the OPB742 include choice of no windows, blue polysulfone windows for dust protection or opaque windows with offset openings for improved resolution.
