Mounting
4.3.1 Checklist for Mounting of contacting Sensors
In the interest of longest lifetime and operational security the following items should be observed
when mounting contacting sensors and checked in regular intervals.
Point of attention
Cable type
Cable routing
Plug
Sensor mounting in the destacking tool
Sensor
Sensorkante
Sensor edge
4.3.2 Spring loaded sensor bracket
P-sensors should always be fitted into spring mounted sensor bracket rather than rigid mounting
arrangements.
A substantial advantage is in the fact that the sensor presents itself perpendicular to the sheet
metal surface even though sensor bracket and sheet surface may not be completely aligned at a
right angle.
It is important to observe that lateral cable pull does not tilt the sensor. In addition it must be
ensured that the springs do not get stuck. If the springs get stuck tilting of the sensor may result or
stuck springs can actually provoke tilting. Ideally the spring mounted bracket should be pre-loaded
in order to ensure that the sensor is presented perpendicular to the sheet even under dynamic
conditions.

Possible influences
1 Use only the recommended cable
with highest flexibility and durability.
2 Avoid any tension of the cable.
Route the cable with enough
clearance.
3 Special care has to be taken to the
route of cable in front of sensor
plug, if a flexible sensor bracket is
used. The cable should never have
a bend close to the plug. Also the
meander of the cable has to be
symmetrically to the axis of the
plug, see enclosed sketch.
4 Correctly tighten the arresting ring
of the plug. This avoids too strong
wear of contacts. If possible choose
a sensor with fixed cable instead.
5 Use a sensor bracket which is
flexible enough to let the sensor
align also to tilted sheets. This
avoids unnecessary wear of sensor
contact surface.
6 Properly adjust sensor edge so that
it aligns with the rubber burls of the
suction cup. Do not allow excess
end. See enclosed sketch. This
avoids unnecessary wear of sensor
contact surface.
7 Properly adjust sensor mounting in
regard to the lifting suction cups of
tooling. Do not allow sensor suction
cup to excess lifting suction cups.
This avoids unnecessary wear of
sensor contact surface.
