Vishay VCNT2030

The VCNT2030 is a reflective sensor in a miniature SMD package. It has a compact construction where the emitting light source and the detector are arranged in the same plane. The emitter uses a vertical cavity surface emitting laser (VCSEL) chip technology with high radiant intensity, high optical power, and high speed. The operating infrared

wavelength is 940 nm. The detector consists of a silicon phototransistor. The sensor’s analog output signal at the phototransistor is dependant on the amount of the light emitted by the VCSEL and reflected of an object in the sensor’s field of view
