All electrical connections of the register sensor are configured as M12
round connectors.
The IP65 protection class is only achieved with screwed plug connectors or
cover caps.
Please observe the following wiring instructions:
• A correct and complete cable shielding concept is required for trouble-
free operation.
• The cable shield must be connected at both ends in the control cabinet
and at the evaluation unit. The cable shield of the pre-assembled cable
is connected to the knurled nut and thus also to the sensor housing.
• The cable shield in the control cabinet must be connected to the operat-
ing ground over a large surface area.
• Appropriate measures must be taken to prevent equipotential bonding
currents flowing through the cable shield.
• Do not lay cables parallel to other cables, especially not to devices with
a high level of radiated emission, such as a frequency converter.
