The R58A Series Registration Mark Sensors detect registration marks in printing and material registration applications often found in the web printing, product packaging and pharmaceutical industries.
It features simplified set-up via potentiometer adjustment of the switching threshold and switch-selectable light/dark operate. The sensor’s short warm-up period, fast 10kHz switching frequency and 15-microsecond repeatability are said to provide reliable detection in high-speed printing and web processing applications, where timing is critical. The sensor’s contrast sensitivity, coupled with its small 1.2x3.8mm sensing image, enables it to detect subtle registration marks on high-gloss and other challenging materials, as well as in low-contrast applications, says the vendor. 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.
