Placement of installation and cabling have decisive influence
on the sensor EMC. Hence correct installation of this active
electronic system and the EMC of the entire system should
be ensured by using suitable metal connectors, shielded
cables and grounding if neccessary. Overvoltages or faulty
connections can damage its electronics despite protection
against wrong polarity.
NOTICE
Never connect / disconnect the sensor when voltage is
applied.

Cable shielding
In the installed condition, the sensor is shielded sufficiently
by the metal hydraulic cylinder. For this reason, no separate
shielding is taken via the M12 connector. If a shielded cable is
used, certain applications may require checking, if both ends
of the shielding must be connected to the machine ground.
When checking, the effect of any high voltage and high fre-
quency field in the vicinity on the shield and on the signals in
the cable should be taken into account.
Machine ground
To ensure proper operation of the sensor, the hydraulic cylin-
der must be connected to the machine ground. Grounding is
often ensured by the mechanical contact between the cylinder
and other machine elements. If the cylinder is connected with
the machine separately, separate grounding, for example via
a grounding strap directly on the cylinder must be ensured.
