VCNT2020傳感器變送器的光學(xué)傳感器-反射式-模擬輸出規(guī)格書PDF中文資料

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.
