3.1.2.2 D-coded M12 Ethernet connectors
You can use M12 connectors with standard screw connection or M12 push-pull connectors
from Phoenix Contact.
3.1.2.3 X-coded M12 Ethernet connectors
You can use M12 connectors with standard screw connection or M12 push-pull connectors
from Phoenix Contact.
Only devices in the 26xx version feature Ethernet ports in D-coding.
Table 3-2 Pin assignment of D-coded M12 connectors
Pin number 10Base-T (10 Mbps) 100Base-T (100 Mbps) Pin assignment
1 TD+ (transmit) TD+ (transmit)
2 RD+ (receive) RD+ (receive)
3 TD- (transmit) TD- (transmit)
4 RD- (receive) RD- (receive)
The figure only shows the pin assignment of the connector but does not give information
on the mechanical alignment during installation.
The shield connection (FE) is implemented via the M12 connector and, depending on the
version, via the metal thread of the push-pull retaining collar.
Only devices in the 27xx version feature Ethernet ports in X-coding and support Gigabit.
Please note: For operation with 1000 Mbps (Gigabit), cables with four twisted pairs
(eight wires), which meet the requirements of CAT5e as a minimum, must be used.
Table 3-3 Pin assignment of X-coded M12 connectors
Pin number 10Base-T (10 Mbps) 100Base-T (100 Mbps) 1000Base-T (1000 Mbps) Pin assignment
