Floating magnets

The floating magnet (➥ ➥ ➥ ➥ ➥ Figs. 3-3 to
3-5) is attached to the moving
member of the machine using non-
magnetizable screws (brass, alu-
minum). To ensure the accuracy of
the transducer system, the moving
member must carry the magnet on a
track parallel to the transducer.
The following table provides figures
in [mm] for the spacing which must
be maintained between magnet and
transducer and for the permissible
center offset:

Captive magnets

Lateral forces are to be avoided
when using captive magnets
(➥ ➥ ➥ ➥ ➥ Figs. 3-6 and 3-7). Connections
are required here which permit the

Ensure that the distance
E between parts made of
magnetizable material and
the BTL5-P-5500-2 magnet is at
least 10 mm ( ➥ ➥ ➥ ➥ ➥ Fig. 3-4).
