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.

Applications

Optoelectronic scanning and switching devices

i.e., index sensing, coded disk scanning etc.

(optoelectronic encoder assemblies for

transmission sensing).

Features

Compact construction in center-to-center spacing

of 0.1’

No setting required

High signal output

Low temperature coefficient

Detector provided with optical filter

Current Transfer Ratio (CTR) of typical 5%
