Compact Luminescence Sensors Earn High Marks for Detecting the Invisible


DK50-UV Luminescence Sensors from Pepperl+Fuchs provide an easy, reliable way to complete tasks such as error checking, sorting, measuring, and positioning materials that blend into a background or are invisible. They detect fluorescent chalk marks, clear glue, tamper-proof seals and other marks that regular contrast sensors cannot, even on irregular backgrounds, and deliver an industry leading (luminescence sensor) sensing range of 600 mm in a space-saving housing that is 50% smaller than previous generation luminescence sensors. A light spot with a small focal point allows you to detect small parts such o-rings, pin-point leaks, and invisible markings down to 2.2 mm diameter targets. These sensors are UL and cUL listed.
