RPR-220 photo interruptor 6mm 800nm

RPR-220 is a reflective photosensor that can detect objects in front of the sensor. The sensor consists of an IR-LED and a phototransistor, mounted side-by-side. When an object is placed in front of the sensor, the light from the LED is reflected back to the phototransistor, which then starts conducting.

Forward voltage, input: 1.34V
Collector-Emitter voltage: 30V
