The 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 210 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.
