Compact Luminescence Sensors Deliver Reliable Detection of Invisible Marks

DK50-UV luminescence sensors provide a simple and reliable means of error checking, sorting, measuring, and positioning materials that blend into a background or are invisible.  They detect marks such as inks, pigments, dyes, coatings, and adhesives -  even on irregular backgrounds - and deliver an industry-leading (luminescence sensor) sensing range of 600 mm in a housing that is 50% smaller than previous generation luminescence sensors.  A small light spot means that even small parts such O-rings, pin-point leaks, and invisible markings can be detected down to 2.2 mm diameter targets.  These sensors are UL and cUL listed.

“DK50-UV sensors can even differentiate between multiple luminescent targets. So, for example, if a user needs to detect a clear luminescent protective seal over a bottle of aspirin with a white luminescent cap, the DK50-UV can distinguish between those two variables and deliver output accordingly,” says Jeff Allison, Product Manager.

DK50-UV luminescence sensors feature up to four automatic teach modes and one manual teach mode, enabling users to customize the sensor to the application (detecting targets, or distinguishing between targets), and to the user (hands-on, or hands-off).  Additionally, the DK50-UV features a graphical, user-friendly, 8-segment LED display that indicates luminescent signal strength, an output mode toggle for quick adjustments, and an integral timer that allows slower controllers to react to sensor output.  They also deliver the industry’s best sensing range relative to housing volume; meaning that there are some smaller competitive models today, but with a significantly shorter available sensing range and limited functionality than is delivered with the DK50-UV.
