RPR220 Optoelectronic Switch

RPR220 Optoelectronic Switch Reflective Optical Coupling Sensor

Product Description:
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.

External dimensions (Units: mm): 260

Sensors: Reflective photosensor (photoreflector) RPR-220
