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.
_Applications
Compact disk 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.
