DGE−...−ZR/−SP
If magnetic proximity sensors SME−... are
used :
· Use the grooves in accordance with
Fig. 28.
· Place the proximity switches with nominal
sizes 8/12/18 with the cable outlet facing
the centre of the stroke.
For DGE−...−SP:
· Observe that the magnet is situated
asymmetrically on the inner slide (on the
side facing away from the motor).
· Avoid external influence caused by
magnetic or ferrite parts in the vicinity of
the proximity sensors (10 mm distance
from the slot nuts).
For DGE−25−SP:
· Place the proximity sensor only in the side
grooves. The magnetic field is very weak
in the lower groove.
For DGE−40−SP:
· Place the proximity sensor SMT−8 (high
response sensitivity) only in the side
grooves. In the top grooves, the magnetic
field is very strong (danger of multiple
switching).
In this way you can ensure that the switches function faultlessly.
