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 highsensitivity, silicon planar phototransistor. A custom lamp was developed to enable the achievement of a smaller package than with conventional reflectors. FApplications Compact disk players, Copiers, Game machines, Office automation equipment FExternal dimensions (Units: mm)
FFeatures 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.
