Description: Colour Mark Sensor emits light and thereby receives the reflecting lights from detected object, and distinguishes the color or recognizes the existence of objects according the intensity of the receiving signals. It can be used in the automatic control systems for packing machinery and can be used with other instruments to detect the existence of the object marked with color code, pattern code, line or others. It is featured with functions like self-locating, recognizing colors, rectifying deviation, pattern checking and countering. These sensors have high sensitivity and have strong anti-background interference. The sensor is compact in structure and quick in response. The sensors implement the optical technique, semi-conductor electronic technique, and modulation demodulation mechanism.
