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%
coverage.
– Connector version: Shield is internally connected to
connector housing.
– Cable version: On the transducer side, the cable
shielding is connected to the housing.
Ground the cable shielding on the controller side
(connect with the protective earth conductor).

Electrical connection

Depending on the model, the electrical connection is made
using a cable (BTL7-...-KA) or a connector (BTL7-...-S32).
The connection or pin assignments for the respective
version can be found in Table 4-2.
Note the information on shielding and cable
routing.

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.
Bending radius for fixed cable
The bending radius for a fixed cable must be at least five
times the cable diameter.
Cable length
BTL7-A Max. 30 m
BTL7-E Max. 100 m
1) Prerequisite: Construction, shielding and routing preclude the effect of
any external noise fields.
