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
corresponding degree of freedom
with respect to the direction of
movement of the magnet along the
stroke range. It is assumed that the
BTL5-F-2814-1S magnet is con-
nected to the machine member
using a connecting rod. The
BTL2-GS10...A connecting rod
(➥ ➥ ➥ ➥ ➥ Fig. 3-8) is available as an ac-
cessory (please indicate length LG
when ordering).

Using several magnets

Maintain the value for a minimal
separation of L > 65 mm between
two magnets:
