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 the magnet and
parts made of magnetizable material is at least 10 mm
(see Fig. 4-4 to Fig. 4-8).
– Maintain the following values for distance B between
the magnet and transducer and for center offset C
(see Fig. 4-4 to Fig. 4-8):
Type of magnet
BTL5-P-3800-2
BTL5-P-5500-2
BTL5-P-4500-1
BTL6-A-3800-2
BTL6-A-3801-2
The selected distance must stay constant over the entire measuring length.
1)
2) For optimum measurement results, a distance B of 6 to 8 mm is
recommended.
