3-3-3 EtherCAT Communications Cable Specifications
Use this connector to connect to a safety device.
Note 1 The recommended cable is a 6-core shielded cable with a wire size of AWG30 to AWG26 and a finished
outer diameter of 6.7 mm or less.
2 For information on wiring, refer to Safety Connector Specifications (CN8) on page 3-23.
For the EtherCAT communications cable, use an Ethernet Category 5 (100BASE-TX) or higher twisted-
pair cable (with double, aluminum tape and braided shielding).
Recommended cable is shown below.
*1 It is recommended that you use this cable in combination with the OMRON XS6G-T421-1 connector.
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.
If an Ethernet cable of Ethernet Category 5 (100BASE-TX) 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.
