EtherCAT wiring

The cable length between two EtherCAT devices must not exceed 100 m.
Cables and connectors
For connecting EtherCAT devices only Ethernet cables that meet the requirements of at least category 5
(CAt5) according to EN 50173 or ISO/IEC 11801 should be used. EtherCAT uses 4 wires for signal transfer.
EtherCAT uses RJ45 connectors. The pin assignment is compatible with the Ethernet standard (ISO/IEC
8802-3).

Due to automatic cable detection (auto-crossing) symmetric (1:1) or cross-over cables can be used between
EtherCAT devices from Beckhoff.
The following Beckhoff cables and connectors are suitable for application in EtherCAT systems:
• ZB9010 (Industrial Ethernet/EtherCAT cable, fixed installation, CAT 5e, 4-core)
• ZB9020 (Industrial Ethernet/EtherCAT cable, suitable for drag chain applications CAT 5e, 4-core)
• ZS1090-0003 (RJ45 connector, 4-pin, IP 20, field-configurable)
• ZS1090-0005 (RJ45 connector, 8-pin (suitable for GigaBit), IP20, field-configurable)
• ZK1090-9191-0001 (0.17 m EtherCAT patch cable)
• ZK1090-9191-0005 (0.5m EtherCAT patch cable)
• ZK1090-9191-0010 (1.0m EtherCAT patch cable)
• ZK1090-9191-0020 (2.0m EtherCAT patch cable)
• ZK1090-9191-0030 (3.0m EtherCAT patch cable)
• ZK1090-9191-0050 (5.0m EtherCAT patch cable)
E-bus supply
Attention! Malfunction possible!
The same ground potential must be used for the E-bus supply of all EtherCAT terminals in
a terminal block!
