Vishay CNY70 Service Manual
Vishay Semiconductors
Reflective Optical Sensor with Transistor Output
Description
The CNY70 has a compact construction where the
emitting light source and the detector are arranged in
the same direction to sense the presence of an object
by using the reflective IR beam from the object.
The operating wavelength is 950 nm. The detector
consists of a phototransistor.
