Telefunken TCST1230 Datasheet
TCST1230
Vishay Telefunken
Transmissive Optical Sensor with Phototransistor
Output
Description
This device has a compact construction where the
emittig-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.
