Registration Mark Sensors For Easy-to-Use, Low-Cost Registration Mark Detection


Banner Engineering Corp. introduces their R58A Series Registration Mark Sensors  for detecting registration marks in printing and material registration applications often found in the web printing, product packaging and pharmaceutical industries. The R58A features simplified setup via potentiometer adjustment of the switching threshold and switch-selectable light/dark operate. The sensor's short warm-up period, fast 10 kHz switching frequency            and 15-microsecond repeatability ensure reliable detection in high-speed            printing and web processing applications, where timing is critical.
“The R58A provides high-performance registration mark detection that is low-cost and easy-to-use,” said Dennis Smith, Technical Marketing Engineer at Banner. “Banner's international and domestic customers require reliable mark detection, easy sensor set-up and fast response time—at a competitive price. The R58A delivers on all these requirements." Smith adds, "As the user adjusts the switching threshold using a potentiometer, two green LEDs guide the user to the optimal setting. The output logic is also user-selectable via a light/dark operate switch, enabling rapid product changeover on high mix printing lines.”
            The R58A's excellent contrast sensitivity, coupled with its small 1.2 x 3.8 mm sensing image, enables the sensor to detect subtle registration marks on high-gloss and other challenging materials, as well as in low-contrast applications. Additionally, the rugged metal housing            and high-quality acrylic lens are designed to handle ambient electrical noise and vibration from presses and die cutting machinery.
            A single emitter color—red or green, specified by model number—ensures that the customer's preferred light source is used every time.
