The frequently used and standardized female connectors M12 allow use of a standard commercial cable to match the
specific, special requirements of the specific operating environment. For example, cables are available which are oil-re-
sistant or suitable for use with drag chains.

resistance to oil) and the matching coding can be used with the controllers.
