Assembling the measuring system

NOTICE
Interference in function
Improper installation of the magnetic tape and sensor
head may impair function of the position measuring
system and lead to increased wear or damage to the
system.
► Strict adherence to permissible distance and angle
tolerances (see sensor head manual is required!
► Make sure that the sensor head does not touch the
magnetic tape or the optional cover strip across the
entire measuring range.
Magnetic fields with ≥ 1 mT reduce the precision of the
system, magnetic fields of ≥ 30 mT destroy the magnetic
tape. The functionality of the system is no longer
ensured.
► Keep external magnetic fields (> 30 mT) away from
the measuring system.
► Avoid direct contact with magnetic retainers or other
permanent magnets!
4.2

Alignment of sensor head to magnetic tape

During assembly, make sure that the sensor head is
correctly aligned to the magnetic tape.
To ensure correct operation or to obtain the required
measurement accuracy, adhere to the assembly
tolerances for the specific application (see sensor head
manual).
To be able to utilize the maximum measuring
length, select the corresponding magnetic tape
length and pay attention to the positioning of
the sensor head to the magnetic tape (see
sensor head manual)!

When positioning the sensor head and
magnetic tape, make sure that they are aligned
correctly to each other. Orientation arrows are
printed on the part label of the sensor head and
magnetic tape for this purpose. These must be
pointing in the same direction.
Alternatively, the orientation of the tape can be
determined using a pole pitch display card
(included with the BAM TO-ML-014-02
mounting accessory, see sensor head manual)
(not for NON-coding, see NON coding A, C
and F on page 9).
The code on the part label of the sensor head
and on the magnetic tape must be identical.
