Installation and connection

4.1 Distances, tolerances and measuring
accuracy
The different mounting tolerances must be met depending
on the required measuring accuracy (see different working
ranges and maximum function range in Tab. 4-1).
During assembly, make sure that the sensor head is
correctly positioned over the magnetic tape. The distances
and tolerances must be complied with to ensure the
correct function and linearity class of the system specific to
the application.
