Magnets, Installation

A magnet is required for each trans-
ducer. This must be ordered sepa-
rately ➥ ➥ ➥ ➥ ➥ Fig. 3-4.
For mounting the magnet we rec-
ommend to use non-magnetizable
material ➥ ➥ ➥ ➥ ➥ Fig. 3-1.

Wiring

Note the following when mak-
ing electrical connections:
System and control cabi-
net 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 control-
ler/master must be connected
using shielded cable.
Shielding: Copper filament
braided, 85 % coverage.
The shield should be grounded
only at the control side in order to
avoid potential compensation –
current flow – over the shield.
Pin assignments can be found in
➥ ➥ ➥ ➥ ➥ Table 4-2.
To avoid coupled noise, avoid prox-
imity to high-current lines when
routing cable between transducer,
controller and power supply. In-
ductive coupled noise from AC
harmonics (e.g., from phase con-
trols) are especially critical,
against which the cable shield
offers very little protection.
The signal is transmitted to the
host controller via the CANopen
interface.
Cable length max. 2500 m;
Ø 6 to 8 mm. The transmission rate
is a function of the cable length.
Corresponding to CiA DS 301, the
following values are valid:
Cable length Baud rate [kBd]
< 25 m 1000
< 50 m 800
< 100 m 500
< 250 m 250
< 500 m 125
< 1000 m 100
< 1250 m 50
< 2500 m 20 / 10
