Contrast (Color Mark) Detection Photoelectric Sensors
Color mark sensors, sometimes called contrast or registration sensors, are highly specialized diffuse proximity photoelectric sensors with the ability to detect subtle surface contrasts. Contrast detection is widely used in packaging and labeling operations to identify various colors of index marks or the presence of labels on shiny surfaces.
Unlike standard energetic diffuse photoelectric sensors, color mark sensors use a highly sensitive lens system positioned at a specific focal distance from a target. These sensors have fast response times and the can detect marks that pass by the sensor at extreme speeds.
Contrast sensors help to precisely cut and punch blister packaging
