Additional Details

The GP2L22B utilizes an infrared LED to emit light and a phototransistor to detect the light beam. When an object interrupts the light beam, the phototransistor switches state, signaling the presence of the object. The compact package and high sensitivity make it ideal for space-constrained applications. The fast response time allows for accurate detection of moving objects. Its key specifications include a forward current of 50mA, collector-emitter voltage of 30V, and operating temperature range of -25°C to +85°C.
