Wenglor P1KH003 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 reflex sensors (PNP/NPN, NC/NO, switching distance) and to output switching statuses and distance values.

Applications

Zone Protection in Stretch Film Systems with Safety Light Arrays

During fully automated packaging of cardboard boxes on Euro pallets in stretch film systems, it is necessary to transport the goods safely into and out of the danger zone, thus avoiding downtimes. Safety light arrays with muting are installed on the conveyor belt for this purpose. With muting activation, the safety light curtain is safely bridged for a short time, so that the pallets can be safely moved in and out for the wrapping process. Further muting functions enable demand-oriented safeguarding of the danger zone, even during muting phases.

Safety Light Arrays for Body Protection

TÜV-certified light curtains provide body protection and prevent people from unintentionally accessing hazardous areas. Depending on the desired risk minimization, various functional scopes can be selected that fulfill all ESPE type 4 in accordance with EN 61496. All models correspond to performance level e according to DIN EN ISO 13849-1.
