EtherCAT Communications Cable Specifications

For the EtherCAT communications cable, use a cable with double, aluminum tape and braided
shielding of category 5 or higher.
Precautions for Correct Use
The maximum length between nodes is 100 m. However, some cables are specified for less
than 100 m. Generally speaking, if the conductors are twisted wire rather than solid wire,
transmission performance will be lower, and reliable communications may not be possible at
100 m. Confirm details with the cable manufacturer.
Reference
If an Ethernet cable of category 5 or higher is used, communications will be possible even if
the cable is not shielded. However, we recommend a cable with double, aluminum tape and
braided shielding to ensure sufficient noise immunity.
Recommended Connector (Modular Plug)
Use a shielded connector of category 5 or higher.
Precautions for Correct Use
When selecting a connector, confirm that it is applicable to the cable that will be used. Confirm
the following items: Conductor size, conductor type (solid wire or twisted wire), number of
twisted pairs (2 or 4), outer diameter, etc.
