VCNT2025X01

VCNT2025X01 is a reflective optical sensor with transistor output. It has a compact construction where the emitting light source and the detector are arranged in the same plane. The operating infrared wavelength is 940nm. The detector consists of a silicon phototransistor. The sensor analogue output signal (photo current) is triggered by detection of reflected infrared light from a close by object. The sensor has a built in daylight blocking filter, which greatly suppresses disturbing ambient light and therefore increases signal to noise ratio. Application includes position sensor, optical switch, optical encoder, object detection (e.g. paper presence in printer and copy machines).
