Installation and connection (continued)
4.4 Electrical connection
The transducer is connected via a connector.
The pin assignments for the respective version can be
found in Table 4-3.
Note the information on shielding and cable
routing.

4.5 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.
Magnetic fields
The position measuring system is a magnetostrictive
system. It is important to maintain adequate distance
between the transducer 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
1) Prerequisite: Construction, shielding and routing preclude the effect of any
external noise fields.
Noise elimination
To avoid equipotential bonding - a current flow - through
the cable shield, please note the following:
– Use insulating bushes
– Put the control cabinet and the system in which the
BTL7 is located to the same ground potential.
