BZJ-311 optical switch Color Mark Sensor

BZJ Series Color Code Sensor applies the light emitting and receiving principle. It will send out modulating light, receive the reflecting lights from detected object, and distinguish the color or recognize the existence of objects according the intensity of the receiving signals. it can serve for sensor in the automatic control systems for packing machinery ,printing machinery ,texture and paper making machinery, etc and be used with other instruments to detect the existence of the object marked with color code, pattern code, line or others. it has the functions of self-locating, recognizing colors, rectifying deviation, pattern high sensitivity, quick response speed, strong anti-background interference, compact structure and convenient opera ion, etc.



1.Compact volume
2.Wide voltage range 
3.Diversified exterior structures

4.high precision of repeated location

5.Good performance of anti-interference.

6.Dust proof,vibration proof,waterproof and Oil-proof.
