Floating magnets

The following must be observed when installing the
magnet:
– To ensure the accuracy of the position measuring
system, the magnet is attached to the moving member
of the machine using non-magnetizable screws
(stainless steel, brass, aluminum).
– The moving member must guide the magnet on a track
parallel to the transducer.
– Ensure that the distance A between parts made of
magnetizable material and the magnet is at least
10 mm (see Figures 4-5 to 4-9).
– Maintain the following values for distance B between
the magnet and transducer and for center offset C (see
Figures 4-5 to 4-9):
Type of magnet
BTL5-P-3800-2 0.1 to 4 mm
BTL5-P-5500-2 5 to 15 mm
BTL5-P-4500-1 0.1 to 2 mm
BTL6-A-3800-2 4 to 8 mm
BTL6-A-3801-2 4 to 8 mm
The selected distance must stay constant over the entire measuring
1)
length.
For optimum measurement results, a distance B of 6 to 8 mm is
2)
recommended.
