Reflective Optical Sensor With Transistor Output
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
