DESCRIPTION
The VCNT2020 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.
The sensor has a built in daylight blocking filter, which greatly suppresses disturbing ambient light and therefore increases signal to noise ratio.

FEATURES
• Package type: SMD
• Detector type: phototransistor
• Dimensions (L x W x H in mm): 2.5 x 2 x 0.8
• Operating range within > 20 % relative collector
   current: 0.2 mm to 2.5 mm
• Emitter wavelength: 940 nm
• Moisture sensitivity level (MSL): 4
• Material categorization: for definitions of
   compliance please see www.vishay.com/doc?99912

APPLICATIONS
• Position sensor
• Optical switch
• Optical encoder (e.g. disc and tape drives for DVD and / or
   camera applications)
• Object detection (e.g. paper presence in printer and copy
   machines)
