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.
