EtherCAT cables
Fig. 31: ZK1090-3131-0xxx
For connecting EtherCAT devices, only use shielded Ethernet cables with a minimum specification of
category 5 (CAT5) according to EN 50173 or ISO/IEC 11801.
Wiring recommendations
Detailed recommendations for EtherCAT cabling can be found in the documentation "Design recom-
mendations for EtherCAT/Ethernet infrastructure", which is available for download from www.beck-
hoff.de.
EtherCAT uses four cable wires for signal transmission.
Due to automatic cable detection (auto-crossing) symmetric (1:1) or cross-over cables can be used between
EtherCAT devices from Beckhoff.
