Sensors 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 highsensitivity, 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 stray light. Applications Copiers Compact disc players Features 1) A plastic lens is used for high sensitivity. 2) A built-in visible light filter minimizes the influence of stray light. 3) Low collector-emitter saturation voltage. 4) Sturdy leads allow easy mounting. 5) Lightweight and compact.
