Luminescence sensors detect invisible materials
DK50-UV Luminescence Sensors from Pepperl+Fuchs provide a reliable way to error check, sort, measure, and position materials that are invisible or blend into a background. They detect fluorescent chalk marks, clear glue, tamper-proof seals and other marks that regular contrast sensors cannot, even on irregular backgrounds, and deliver a sensing range of 600 mm in a space-saving housing that is 50 percent smaller than previous generation luminescence sensors. A light spot with a small focal point allows you to detect small parts such as o-rings, pin-point leaks, and invisible markings down to 2.2 mm diameter targets. These sensors are UL and cUL listed.
These sensors have up to four automatic teach modes and one manual teach mode, allowing OEMs to customize the sensor to the application (detecting targets or distinguishing between targets), and to the user (hands-on or hands-off). The sensors feature a graphical, user-friendly 8-segment LED display. This display indicates luminescent signal strength, uses an output mode toggle for quick adjustments, and comes with an integral timer that allows slower controllers to react to sensor output.
