The featured color-code sensor applies the light emitting and receiving principles. It will send out modulating light, receive the reflecting lights from detected object, and distinguish the color or recognize the existence of objects according to the intensity of the receiving signals. The sensor can be applied on packing machinery, printing machinery, texture and paper making machinery, etc.

• Can be used with other instruments to detect the existence of the object marked with color code, pattern code, line or others. 
• Applies optical technique, semiconductor electronic technique and modulation demodulation.
• Self-locating.
• Recognizing color.
• Rectifying deviation.
• Pattern checking.
• Countering.
• High sensitivity.
• Quick response speed.
• Strong anti-background interference.
• Compact structure.
• Convenient operation.
