Details of the M12 connections of the SK
TU4-CAO-M12
The special wiring of the M12 round plug connector
enables the connection of both single and double
sensors, which are equipped with normal M12
system connectors in the standard sensor/actuator
configuration.
With the use of M12 round plug connectors, the
terminal bar connectors
for the digital inputs
(Terminals 19, 20, 25, 26) must not be used.
