Incremental magnetic encoder system
Installation and connection
Sensor head and magnetic tape
During assembly, make sure that the sensor head is
correctly aligned to the magnetic tape.
The magnetic tape is not included in the scope
of delivery and must be ordered separately.
When selecting the magnetic tape, make sure
that the magnetic tape and sensor head are
compatible. This particularly applies to the
following:
– Pole width
– Reference points
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
assembly accessories).
To ensure correct operation or to obtain the
required measurement accuracy, adhere to the
assembly tolerances for the specific application.
The values in the table below apply for the
recommended alignment. The mechanical
tolerances and measurement accuracy can be
obtained from the detailed user's guide.
