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.

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.

APPLICATIONs
    Compact disk players, Copiers, Game machines, Office automation equipment
