To ensure protection against short-circuits/overload in the customer’s supply cables,
the wire cross-sections used must be appropriately selected and protected.

Wiring the interfaces
5.5.1
Wiring the digital inputs
Pin 5 can be used as a digital input for an external teach-in or for changing the reading
and edge searching direction.
Voltage level at the input starts the corresponding function of the device.
Electrical values
High: 12 V ≤ U ≤ U
V
Low: 0 V ≤ U ≤ 9 V
5.5.2
Wiring the digital outputs
In each case, the digital outputs are short-circuit protected and overcurrent protected.
Push/pull switching behavior
Electrical values
The sum current (100 mA) must be switched on for all digital outputs.
Push/pull
High: VS − 3 V
Low: ≤ 3 V
In the case of a push/pull sensor with PNP switching behavior, the signal must be
inverted in the control system in order to obtain the same result as a sensor with NPN
switching behavior.
