6.4 Application examples for position monitoring
6.4.1 Fine adjustment of the end position
The signal strength of the device depends on how much of the sensing face is covered by the switching
cam on the cylinder piston.

Fig.10: Fine adjustment of the end position
A: Full coverage C: No coverage
B: Low coverage
At full coverage (A), the measured value PDV1 is low, at low coverage (B), it is higher. The switch point
for an end position can be set in the application based on the actual coverage. This means that installa-
tion-related tolerances etc. are not taken into account, resulting in a more precise switching signal in the
end position.
To prevent a hard stop of the piston or application in the end position, the switch point can be set before
the mechanical end position (C).
By monitoring the measured value PDV1, signs of wear or contamination in the application can be detect-
ed. For this purpose, the signals from (A) and (B) must be compared and the switching signals set accord-
ingly.
6.4.2 Linear measurement with conical switching cam
The measuring range can be increased using a conical switching cam.
Due to the inclined geometry, the sensing face coverage or distance between the sensing face and the
target changes less when the piston rod moves accordingly.

When the device is used in a brake cylinder, the
extended measuring range can be used to detect
whether the brake is applied and how far the pis-
ton extends. This can be used to determine how
worn the brake linings are.
6.4.3 Monitoring a high pressure valve
The device can be used in various high pressure applications. For example, on a high-pressure valve, the
device can monitor the closing function and detect blockages or contamination.
