Micropulse AT Transducer in round profile housing
3 Installation (cont.)
3.1

Transducer installation

Ensure that no strong
electrical or magnetic
fields are present in the
immediate vicinity of the trans-
ducer.
Any orientation is permitted.
Mount the transducer on a level
surface of the machine using the
mounting brackets. Observe the
recommended spacing of the
mounting brackets, dimension
➥ ➥ ➥ ➥ ➥ page 3.
1. Align transducer slot with mag-
net.
2. Tighten mounting screws to a
maximum of 3 Nm.
3.2

Magnet installation

To ensure the accuracy of the trans-
ducer system, the magnet is at-
tached to the non-magnetizable
moving member of the machine
using non-magnetizable screws
(stainless steel, brass, aluminum).
The moving member must guide the
magnet on a track parallel to the
transducer.
Ensure that the distance " A " be-
tween parts made of magnetizable
material and the magnet is at least
10 mm (➥ ➥ ➥ ➥ ➥ page 3). Maintain the
following values in [mm] for distance
" B " and center offset " C " be-
tween the magnet and the trans-
ducer (➥ ➥ ➥ ➥ ➥ page 3):
For optimum performance, a dis-
tance " B " of 6 ... 8 mm is recom-
mended.

Wiring

Note the following when mak-
ing electrical connections:
System and control cabi-
net must be at the same
ground potential.
To ensure electromagnetic com-
patibility (EMC), which Balluff
verifies by the CE Marking, the
following points must be strictly
observed.
• BTL transducer and the proces-
sor/control must be connected
using shielded cable.
• Shielding: Copper filament
braided, 80% coverage.
• The cable shield must be
grounded on the control side,
i.e., connected to the protection
ground.
Pin assignments can be found in

When routing the cable between the
transducer, controller and power
supply, avoid proximity to high volt-
age lines to prevent noise coupling.
Especially critical is inductive noise
caused by AC harmonics (e.g. from
phase-control devices), against
which the cable shield provides only
limited protection.

Table 4-1: Wiring assignment
High noise immunity on the line
between the transducer and proces-
sor is provided by the differential
line drivers used for the RS 422
interface. The signal is processed
by the controller or made available
by the processor card in the form of
analog or digital information.
Cable length max. 500 m.
