Booklet labels contain more information with the drawback, however, of increasing their thickness and not flowing smoothly into traditional fork sensors. With its 50x5 mm slot size, Datasensing’s SR23 is the ideal fork sensor for detecting thick multi-layer booklet labels used in food and pharma packaging. SR23 is the best for high-speed and compact labeling machines, thanks to its 12 kHz switching frequency and compact metal housing with IP65 protection.
