RPR220详细

RPR-220 Sensors 1/3 Reflective photosensor (photoreflector) RPR-220 The RPR-220 is a reflective photosensor. The emitter is a GaAs infrared light emitting diode and the detector is a high- sensitivity, silicon planar phototransistor. A custom lamp was developed to enable the achievement of a smaller package than with conventional reflectors. !!!!Application Compact disc players, Copiers, Game machines, Office automation equipment !!!!Features 1) A plastic lens is used for high sensitivity. 2) A built-in visible light filter minimizes the influence of stray light. 3) Lightweight and compact. !!!!External dimensions (Units : mm) 1.
