The infrared LED and photologic sensor are housed in an opaque housing to reduce ambient light sensitivity. The sensor window is transparent to near-infrared wavelengths and protects the sensor in dusty environments. The sensor output is npn open-collector and features a maximum collector voltage of 30 V, collector current of 50 mA, and power dissipation of 250 mW. Operating temperature is from 0 to 50°C.
