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 ap-
plications 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 frequency field in the vicinity on the shield and
on the signals in the cable should be taken into account.
- Electrical power supply from battery (charged by generator)
- Load dump protection and EMC requirements acc. to vehicle standards

Machine ground
To ensure perfect operation of the sensor, the hydraulic cylinder must
be connected to the machine ground. Equipotential bonding is often
ensured by the mechanical contact between the cylinder and other
machine elements. If the cylinder is connected with the machine sepa-
rately, separate grounding, for example via a grounding strap directly
on the cylinder must be ensured.
