DESCRIPTION
The OPB703W, OPB704W and OPB705W 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. Leads are 26 AWG, PVC insulation, 4.5" (114.3 mm) minimum length, stripped and tinned.
