Luminescence sensors support packaging applications

The DK50-UV Luminescence Sensors (photo) provides a 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 detect, even on irregular backgrounds. These sensors deliver a sensing range of 600 mm in a space-saving housing that is 50% smaller than previous generation luminescence sensors, says the company. A light spot with a small focal point allows users to monitor small parts, such as O-rings, pinpoint leaks, and invisible markings down to 2.2-mm-dia. targets. These sensors are UL and cUL listed. The DK50-UV can also differentiate between multiple luminescent targets. Its graphical eight-segment LED display, which indicates luminescent signal strength, and other key parameters. It comes with an integral timer that allows slower controllers to react to sensor output. — Pepperl+Fuchs, Twinsburg, Ohio
