Ultrasonic Sensor Monitors Die-Cut Sheets and Foils for Chip Cards

In the production of chip cards, PCB panels are printed and punched using a punching tool before they are stacked for packaging. Before transfer to a magazine, the sheets must be reliably detected in order to maintain a constant flow of material. Ultrasonic sensors ensure reliable detection of laminated, perforated and stamped sheets regardless of their color and surface – even transparent materials with numerous recesses are easily detected.
