VCNT2020 Low-Profile Reflective Sensor with Analog Output

Vishay combines an emitter and phototransistor into a single package

Image of Vishay's VCNT2020 Low-Profile Reflective Sensor with Analog Output Vishay's VCNT2020 is a reflective sensor in a miniature SMD package. It has a compact construction where the emitter and detector are arranged in the same plane. The current output of the sensor is triggered when the emitted infrared light reflects off a nearby object. The operating infrared wavelength is 940 nm. The detector consists of a silicon phototransistor. The sensor has a built-in daylight blocking filter, which greatly suppresses disturbing ambient light and thereby increases signal to noise ratio.

Features
  • SMD package with height of only 0.8 mm
  • Phototransistor output
  • Dimensions: 2.5 mm x 2 mm x 0.8 mm
  • Emitter wavelength: 940 nm
  • Operating range within > 20% relative collector current: 0.2 mm to 2.5 mm
Applications
  • Position sensor
  • Object detection (e.g. paper presence in printer and copy machines)
  • Optical switch
  • Optical encoder (e.g. disc and tape drives for DVD and/or camera applications)
