APPLICATIONS
• Position sensor
DESCRIPTION
• Optical switch
The VCNT2025X01 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 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.
• Optical encoder
• Object detection (e.g. paper presence in printer and copy
machines)
The sensor has a built in daylight blocking filter, which
greatly suppresses disturbing ambient light and therefore
increases signal to noise ratio.
