The pre-assembled extension of a basic cable has an M12 plug (IP67) and an M12 socket
(IP67).

Note
Maximum number of extensions
A maximum of two extensions can be used. More than two extensions can result in data
transfer errors.
Note
Maximum permissible total cable length
The maximum permissible total cable length between the measuring system and the DRIVE-
CLiQ socket of the SINAMICS S120 device is 30 m. For a longer total cable length, data
transfer errors may occur. This is the reason that no additional extension can be connected
to a 30 m long basic cable.
