Details of M12 connections of the SK TU4-DEV-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
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.
