.vishay. Vishay Semiconductors Reflective Optical Sensor with Transistor Output 17091-2 Cath Coll Top view DESCRIPTION The TCNT2000 is a reflective sensor in a miniature SMD package. It has a pact construction where the emitting light source and the detector are arranged in the same plane. The operating infrared wavelength is 940 nm. The detector consists of a silicon phototransistor. The sensor analog 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...
