These are special color mark sensors that sense colour. It is based on the principle that every colour has its own intensity. They cast out modulated ray toward the required article. When the ray falls on the article it reflects the ray which is sensed by the sensor and colour detection is carried out on the basis of the intensity of the reflected ray. We supply high quality sensors that manufactured by Datalogic, Banner and Visolux company which are perfect for sensing, displaying as well as representing images on electronic systems. These Print Mark Sensor and colour mark sensors are very operational in a variety of industries and are cost-effective.
