Transmissive Optical Sensor
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 detector
consists of a photologic-IC with Schmitt trigger and
open collector output.
Applications
D
Detection of opaque material, documents etc.
D
Paper position sensor in copy machines
D
Position sensor for shaft encoder
