Reflective photosensor (photoreflector) RPR-359F The RPR-359F is a reflective photosensor. The emitter is a GaAs infrared light emitting diode and the detector is a high-sensitivity, silicon planar phototransistor. A plastic lens is used for high sensitivity. In addition, since it is molded in plastic with a visible light filter, there is almost no effect from stay light.
