Magnets, Installation

A magnet is required for each trans-
ducer. This must be ordered sepa-
rately. ➥ ➥ ➥ ➥ ➥ Fig. 3-5.
For mounting the magnet we recom-
mend to use non-magnetizable
material. ➥ ➥ ➥ ➥ ➥ Fig. 3-1.

To avoid coupled noise, avoid prox-
imity to high-current lines when rout-
ing cable between transducer, con-
troller and power supply.
Inductive coupled noise from AC
harmonics (e.g., from phase
controls) are especially critical,

against which the cable shield offers
very little protection.
Max. cable length 20 m. Longer
cables may be used if their
construction, shielding and routing
prevent noise interference. The
cable must be routed strain-
relieved.

Wiring

Note the following
when making electrical
connections:
System and control cabinet must
be at the same ground potential.
To ensure the electromagnetic
compatibility (EMC) which Balluff
warrants with the CE Mark, the
following instructions must be
strictly followed.
• BTL transducer and the proces-
sor/control must be connected
using shielded cable.
• Shielding: Copper filament
braided, 85% coverage.
• The shield must be tied to the
connector housing in the BKS
connector
Pin assignments can be found in
➥ ➥ ➥ ➥ ➥ Table 4-1.
