3.4 CONNECTIONS
The connector faceplate diagram is shown in, which also shows a schematic of the possible
interconnections. The specifications for the individual connections are given in the following
subsections.
3.4.1 LAN (Ethernet / PoE+)
The LAN connector is a 4-pair, 26 AWG stranded (7-wire), M12 flush-type socket. The LAN connector
can serve for communications and/or IEEE 802.3at power over ethernet (PoE+). This connector supplies
both the communications interface and the required power supply.
External cables are available from a wide variety of vendors in many lengths with unterminated, M12,
RJ45, or other end terminations. An example from Phoenix Contact in 10-meter length is part number
1440630.
