EtherCAT – General information on wiring
The wiring uses the Industrial Ethernet fieldbus cable common in industry. For the AMS 338
i
,
the EtherCAT connection is made via D-coded M12 connectors. A Cat. 5 Ethernet cable
should be used for wiring.
Leuze electronic offers cables ready-made and featuring a D-coded M12 connector on one
end and an open cable end at the other.
For further information, see chapter 7 "Electrical connection" and see chapter 11.3.5
"Accessory ready-made cables for EtherCAT".
The individual AMS 338
i
devices in a line topology are connected to each other using the
"KB ET - … - SSA" cable with ready-made D-coded M12 connectors on both ends, see
table "Order codes for EtherCAT connection cables" on page 88.
For unavailable cable lengths, you can configure your cables yourself. For this purpose,
Leuze electronic offers a D-coded M12 connector for Bus IN and Bus OUT. When doing
so, make certain that you connect
TD+
on the M12 connector with
RD+
on the RJ-45
connector and
TD-
on the M12 connector with
RD-
on the RJ-45 connector, respectively,
etc.
For the connection technology transition from M12 to RJ45, a "KDS ET M12 / RJ 45 W - 4P"
adapter is available.
