Precautions for Correct UsePrecautions 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.
• 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.
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.
*1 Cables are available in the following lengths: 0.3, 0.5, 1, 2, 3, 5, 10, and 15 m. Refer to the Industrial Ethernet
Connectors Catalog (Cat. No. G019) for details.
