Floating magnets

Observe the following when installing the magnet:
– To ensure the accuracy of the magnetostrictive linear
position sensor, fasten the magnet to the moving
member of the machine only using non-magnetizable
screws (stainless steel, brass, aluminum).
– The moving member must guide the magnet on a
parallel line to the BTL.
– Distance A between the magnet and parts made of
magnetizable material must be kept to at least 10 mm
(see Fig. 5-4 to Fig. 5-8).
– For distance B between the magnet and the BTL and
for the center offset C (see Fig. 5-4 to Fig. 5-8) the
following values must be maintained:
Magnet type
BTL5-P-3800-2
BTL5-P-5500-2
BTL5-P-4500-1
BTL6-A-3800-2
BTL6-A-3801-2
The selected distance must remain constant over the entire measuring

length.
For optimal measurement results: 6...8 mm
