DESCRIPTION
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.
