Chapter 3
Switch Output Configuration
The sensor measures five different physical values. These values can be
independently adjusted and used as source for the Switching Output 1 or 2, in
addition to those an external input can be selected for SO2. After selecting one
of these sources, it is possible to configure the output of the sensor with an
IO-Link master following the steps that are shown in the Switching Output
configuration (Figure 3).
Once the sensor has been disconnected from the master, it switches to the SIO
mode and keeps the last configuration setting.

Chapter 3 Switch Output Configuration
Sensor Front When an object (solid or liquid) approaches the face of the sensor, the
capacitance of the detecting circuit is influenced and the sensor output
changes its status.
SSC (Switching Signal Channel)
For presence (or absence of presence) detection of an object in front of the face
of the sensor, the following settings are available: SSC1 or SSC2.
The setpoints can be set from 0…10,000 units that represent the change of
capacitance of the detecting circuit. The higher value, the closer the target
appears to the sensing face of the sensor, also a higher dielectric value of the
target increases the value. For example, a metal target has a higher dielectric
value than a plastic target.
Switchpoint Mode
The switchpoint mode setting can be used to create more advanced output
behavior. The following switchpoint modes can be selected for the switching
behavior of SSC1 and SSC2.
Mode Description
Disabled SSC1 or SSC2 can individually be disabled, which also disables the output if it is
selected in the input selector (the logic value is always 0).
Single-point mode
The switching information changes, when the measurement value passes the
threshold that is defined in setpoint SP1, with rising or falling measurement values,
considering the hysteresis.
Two-point mode
The switching information changes when the measurement value passes the threshold
that is defined in setpoint SP1. This change occurs only with rising measurement
values. The switching information also changes when the measurement value passes
the threshold that is defined in setpoint SP2. This change occurs only with falling
measurement vales. Hysteresis is not considered in this case.
Window mode
The switching information changes, when the measurement value passes the
thresholds that are defined in setpoint SP1 and setpoint SP2, with rising or falling
measurement values, considering the hysteresis.
