Shielding and cable routing

Defined ground!
The transducer and the control cabinet must be
at the same ground potential.
Shielding
To ensure electromagnetic compatibility (EMC), observe
the following:
– Connect transducer and controller using a shielded
cable. Shielding: Braided copper shield with
minimum 85%.
– Shield is internally connected to connector housing.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the transducer/holding cylinder and strong,
external magnetic fields.
Cable routing
Do not route the cable between the transducer, controller,
and power supply near high voltage cables (inductive stray
noise is possible).
The cable must be routed tension-free.
Cable length
The maximum cable length when using CAT5e cables is
100 m .

Prerequisite: Construction, shielding and routing preclude the effect of any

external noise fields.
