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 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.

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.
