The reflex sensor makes use of a red light line in accordance with the energetic principle and is suitable for detecting objects without any background. It’s suitable for reliable detection of objects with stamped or perforated surfaces such as PCBs and perforated sheet metal. Furthermore, objects can be detected on the light line regardless of position. The IO-Link interface can be used to configure the reflex sensor (PNP/NPN, NC/NO, switching distance), as well as for reading out switching statuses and distance values.
