DESCRIPTION
The OPB703, OPB704 and OPB705 consist of an infrared emitting diode an an NPN silicon phototransistor mounted side by side on converging optical axis in a black plastic housing. The phototransistor response to the radiation from the emitting diode only when when a reflective object passes within its field of view. The area of the optimum response approximates a circle .200" in diameter.
