Installation and connection (continued)
4.3 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4-3 to4-7).
– Maintain the following values for distance B between
the magnet and transducer and for center offsetC (see
Figures4-3 to4-7):
Type of magnet DistanceB
1)
OffsetC
BTL5-P-3800-2 0.1…4mm ±2mm
BTL5-P-5500-2 5…15mm ±15mm
BTL5-P-4500-1 0.1…2mm ±2mm
BTL6-A-3800-2 4…8mm
2)
±5mm
BTL6-A-3801-2 4…8mm
2)
±5mm
1)
The selected distance must stay constant over the entire measuring length.
2)
For optimum measurement results, a distanceB of 6 to 8mm is
recommended.
