Contrast sensors

Contract sensors can detect and compare precise contrasts. The devices are used for reliable, precise detection of printed marks using color and grayscale contrasts on the most varied carrier materials such as labels, films, banderoles, cartons or tubes. The devices are configured through intuitive teaching-in.


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.
