Warning
Danger of crushing or shearing due to travel of the protruding switch
lug
1/2 over the proximity sensor (C).
• Avoid
reaching into the travel area of the switch lug
1/2, e.g. by means
of a protective guard.

Adjustment
Note
If set correctly there will be a gap of S = 0.1 … 1.5 mm between the prox-
imity switch (B)/(C) and the switch lug
1/2.
• Also observe the technical data of the proximity sensors (B)/(C) to this
end.
For linear axes with plain-bearing guide, the distance S can change through
wear of the guide.
• Regularly check the dimension S (every 500 km).
• Avoid external influence in the vicinity of the proximity switches caused
by magnetic or ferritic parts other than the switch lug
1/2.
