Wenglor P2KH002 Reflex Sensor with Background Suppression

Wenglor P2KH002 Reflex Sensor with Background Suppression

The reflex sensor with background suppression works with red light according to the angle measurement principle and is suitable for the detection of objects against any background. The sensor always has the same switching distance, regardless of the color, shape, and surface of the objects. Minimal height differences can be detected with the sensors and, for example, various parts can be reliably differentiated from each other. The IO-Link interface can be used to configure the reflex sensors (PNP/NPN, NC/NO, switching distance), as well as to output switching statuses and distance values. The robust V4A (1.4404/316L) stainless steel housing is resistant to oils and coolants, as well as cleaning agent.

Applications

Detection of Cookies with Reflex Sensors with Background Suppression

In the production of cookies, the objects must be transported and gripped between different processes on multi-lane conveyor belts. After baking in the oven, they are individually conveyed on rails and prepared for the packaging process. They must be counted before gripping and moving. For this purpose, a reflex sensor with background suppression is installed above each lane on the conveyor line, which detects the cookies from the front edge. Thanks to the stainless steel 316L housing, the sensors are ideal for hygienically demanding cleaning at high temperatures.

Reflex Sensors With Background Suppression

Reflex sensors with background suppression detect and measure objects contactlessly and detect them in front of any defined background. They work with red light, infrared light, blue light or laser light. Thanks to the principle of angle measurement, the color, shape and object surface have no influence on the switching behavior of the sensors.
