OPB740

OPB 740 Series Reflective Object Sensors Description The OPB740 through OPB744 series of reflective object sensors each consist of an infrared emitting diode and an NPN silicon phototransistor mounted side by side on converging optical axes in an black plastic housing. Various options include choice of no windows, blue polysulfone windows for dust protection or opaque windows with offset openings for improved resolution. Available with wires as OPB740W / OPB744W series. The OPB 745 reflective object sensor consists of an infrared emitting diode and an NPN silicon photodarlington .
