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).

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 hole: BTL threads are M18×1.5 (ISO) or 3/4"-
16UNF (SAE). Depending on the version, a mounting hole
must be made before assembly.

Fig. 4-4: Mounting hole 3/4" 16UNF per SAE J475 O-ring 15.3x2.4
Magnet: Various magnets are available for the BTL (see
Accessories on page 25).
