A.1 Connector system M12/X-coded according to IEC 61076-2-109
Description
M12 connectors with X coding are also suitable for transmission rates up to 10 Gbps (Cat6A)
because the shields of the wire pairs can be led into the connectors. A further advantage is the
availability of connectors with degree of protection IP67 with which the equipped devices are
also suitable for adverse environmental conditions (dust, dampness). Due to the locking
technology standardized for the M12 connectors a high resistance to vibration is achieved.
Numerous SCALANCE devices therefore provide connection options for X coded M12
connectors.
