Emitter and Detector
Description
TCZT8020
Vishay Telefunken
Matchable Pairs – Emitter and Detector
Description
Pairs of infrared-emitting diode and phototransistor, matched in their optical and electrical features.
These pairs enable a lot of applications.
They can be used both for transmissive or reflective sensor functions.
The peak wavelength of the emitter is l = 950 nm.
Applications
D Generally used for industrial processing and
controlling, end of tape detector
Features
D Subminiature case with lens D Detector with optical filter, protected against
ambient light
