Alternative earthing concept 

 

With the alternative earthing concept, the sensor cable shield is connected to the sensor 
housing. The sensor housing is uncoupled from the machine earth by means of an EMC 
adapter (red). With the alternative earthing concept, an electrically secure earth connection can 
only be ensured for versions with an M12 plug connection. For versions with an integrated 
cable, the alternative earthing concept cannot be used.

Please advise us if you are opting for the alternative earthing concept when 
enquiring. We will offer you the relevant sensor cable and the EMC adapter.
