Contrast sensors can detect and compare precise contrasts. The devices are used for reliable, position-precise detection of printed marks using color and grayscale contrasts on carrier materials such as labels, cartons or tubes.
These OK-50 contrast sensors have a robust metallic housing with a high protection class. The sensors work with white-light (LED) and detect even the finest of contrasts. Their sensitivity can be adjusted in an easy and user-friendly manner with a teach-in button.
