TCST1000/ TCST2000
Vishay Telefunken
Transmissive Optical Sensor without Aperture
Description
This device has a compact construction where the
emitting-light sources and the detectors are located
face-to-face on the same optical axis.
The operating wavelength is 950 nm. The detector
consists of a phototransistor.
