6 Function
The device provides the following functions and signals them with a switching signal:
• Monitoring the piston position in hydraulic cylinders
• Diagnostic functions:
– Switching cycles counter
20
– Operating hours counter
21
– Switch-on operations
21
– Internal temperature
21
Two physical switching outputs are available.
• The switching channel SSC1.1 is permanently assigned to the output OUT1.
• The switching channel SSC1.2 is permanently assigned to the output OUT2.
6.1 Measuring principle
The device detects a change in the magnetic field caused by the approach of a ferromagnetic or magnetic
target.

1: Magnetic field without target
2: Ferromagnetic target
3: Magnetic field with target
When using a standard target made of iron (12x12x1 mm) and approaching along the axis, the calculated
output signal is linear and proportional to the position of the target.
Ferromagnetic materials such as iron, permanent magnets and magnetic fields in the vicinity of
the device and of the encoder magnet can influence and falsify the signal.
6.2 Signal range
The device outputs a measured value PDV1, which depends on the position of the target in the range
from 0 to 200. This value is dimensionless, but proportional to the position of the target.
When using a standard target, the measuring range is 2 mm. The shape and material of the target can in-
fluence the size of the measuring range and its linearity.
6.3 Switching signal
The device provides digital switching signals via switching signal channels (SSC = Switching Signal Chan-
nel).
The device has 2 digital switching channels SSC1.1 and SSC1.2.
The switching channels can be analysed via the IO-Link interface and the hardware outputs.
The switching signal channels are permanently assigned to the physical hardware outputs:
• SSC1.1 to OUT1
• SSC1.2 to OUT2
