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 brackets
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 present 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.
