With the DRT 25C dynamic reference diffuse sensor, Leuze has brought a new operating principle to the market in the area of optical sensors. At the heart of the invention is the innovative CAT technology, which transforms a simple diffuse sensor into a highly intelligent device. This can be seen in the DRT 25C’s clever mode of operation: it is taught in on a reference surface at the press of a button which allows it to reliably detect nearly every object – independent of shape, color and surface structure. The reference surface can be a machine wall, a piece of sheet metal, or even a vibrating, moving conveyor belt. This makes the sensor particularly well suited for use in packaging systems, especially in the area of confectionery and baked goods. No readjustment is necessary when changing objects.
Leuze developed its first optical sensor almost 60 years ago. Numerous technological milestones and innovations have followed since then. The more than 1,200 Sensor People worldwide view themselves as forerunners for their customers. Leuze has registered more than 200 patents in the last 10 years alone. This all with the goal of ensuring the lasting success of their customers in an industry that is ever evolving. Not only do the Sensor People have decades of experience but also in-depth application know-how in their specific focus industries. One of these is the packaging industry, which, with throughputs of several hundred thousand products per day and finely tuned process steps, places extremely high demands on the optical sensors. Clear-glass retro-reflective photoelectric sensors require less maintenance through smart tracking. Thanks to line-shaped light spots, laser diffuse sensors detect objects – no matter how complex – on their front edge. Extremely powerful through-beam photoelectric sensors detect the chocolate bar in its outer packaging with completely harmless infrared light. The intelligent CAT technology, which the new DRT 25C dynamic reference diffuse sensor uses, continues the idea of the clever sensor.
