Magnetizable material
If using magnetizable material, the BTL must be protected
against magnetic interference through suitable measures
(e.g. spacer ring made of non-magnetizable material, a
suitable distance from strong external magnetic fields).

4.2 Preparing for installation
Installation note: We recommend using non-
magnetizable material to mount the BTL and magnet.
Horizontal assembly: For horizontal assembly with
nominal lengths > 500 mm, support the rod and tighten it
at the end if necessary (only possible with a diameter of
10.2 mm).
Hydraulic cylinder: If installed in a hydraulic cylinder,
ensure that the minimum value for the bore diameter of the
support piston is complied with (see Tab. 4-1).
Fitting bore: The mounting surface of the BTL must make
full contact with the supporting surface. A suitable O-ring
must completely seal the bore, i.e. the countersink for the
O-ring must be produced in accordance with Fig. 4-3.
