To ensure protection against short-circuits/overload in the customer’s supply cables,
the w
ire cross-sections used must be appropriately selected and protected.
5.5 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 ed
g
e searching direction.
Voltage level at the input starts the corresponding function of the device.

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 sw
itching behavior
Electrical values
The sum c
urrent (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
in
v
erted in the control system in order to obtain the same result as a sensor with NPN
switching behavior.
