Product description
“Two switch points”
Switching output 1 and switching output 2 can be used and set to separate switching distances
in 20% increments. A variable hysteresis cannot be set for the “Two switch points” function.
“Low resolution analog mode”
NOTE
The low resolution analog mode can only be used in operation on an IO-Link master.
In low resolution analog mode the switching states are sampled sequentially in 20% incre-
ments. This provides distance information which is output via Bit 2…Bit 4 of the process data in
binary format.

NOTE
Output 2 can be configured as required or can be used as a temperature indicator. The
maximum switching frequency is reduced to 7 Hz in low resolution analog mode.
“Rotational speed monitor”
The “Rotational speed monitor” enables the device to detect frequency values below and above
a specified frequency window. Upper and lower limit values of the frequency window can be
set between 0 and 30000 pulses per minute. The switching behavior is described in Fig. 6.

The actual speed can be queried via the acyclic IO-Link parameter data. The tolerance is 3 %.
The switching distance is permanently set to S
