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).
Mounting threads: The BTL comes with an M18×1.5
(according to ISO) or a 3/4"-16 UNF (according to SAE)
thread to secure it. Depending on the version, a mounting
hole must be made before assembly.
