This contrast sensor detects differences in print contrast on labels and packaging within a 6-12mm sensing range, making it suitable for print mark detection and registration tasks on packaging or labelling lines. The housing is aluminium die-cast with a PMMA sensing surface, and the unit operates from a 10-30VDC supply with PNP/NPN switching output configurable for normally open or normally closed operation. It offers a switching frequency of 15000Hz, allowing use in applications requiring fast object or mark detection.
