P2KH031 Reflex Sensor with Background Suppression
Available from stock
Added to Your Cart:
The reflex sensor with background suppression works with laser light according to the angle measurement principle. It has an IO-Link interface with a data storage function as well as additional configuration and diagnostic options. The interface can also be used to configure the sensors (PNP/NPN, NC/NO, switching distance, error output), as well as for reading out switching statuses and distance values. Two independent switching outputs can be used, for instance, to monitor minimum and maximum values of distances or fill levels and stack heights. The robust V4A (1.4404/316L) stainless steel housing is resistant to oils and coolants, as well as cleaning agent.
