P1PM103 Reflex Light Barrier

Available from stock
The reflex light barriers work with red light and detect objects both via the intensity of the backscattered light and via the distance to a previously taught-in reference background. Thanks to the combined detection principle, the sensors are suitable for contactless object detection without a reflector, regardless of color, shape or surface. Due to their large range, reflex light barriers enable ejection and presence check applications as well as object detection on wide feed belts. The IO-Link interface can be used to configure reflex light barriers (PNP/NPN, NC/NO, teach-in mode) as well as for reading out switching statuses.
