TCVT1300

Vishay Telefunken

Dual Channel Transmissive Optical Sensor with
Phototransistor Output

Description

This device has a compact construction where the
emitting-light sources and the detectors are located
face-to-face on the same optical axes. The operating
wavelength is 950 nm.
The detectors consists of a phototransistors. The
distance of both channels is 2.66 mm.
