Ethercat Cable Specification

The goal during development of ethercat was to apply ethernet for automation applications requiring short data update times also.

Ethercat cable specification.

Ethercat network is normally composed of one master for example industrial pc and some slaves for example servo drives filed bus terminals and so on. Every ethercat slave has two standard ethernet interfaces. Ethercat uses rj45 connectors. P stands for power and enables one to use the standard 4 wire ethernet cable not only for data but also for two electrically isolated individually switchable 24v 3a power supplies.

Ethernet and ethercat cables and connectors. Special cables are to be used for drag chains or garlands. Large variety of cable qualities. Cat6 cable is a major improvement over cat5e.

Pre wired and molded models for rj45 m8 m12 d x y coded. The cable screen must not be used for strain relief. Ethercat uses 4 wires for signal transfer. The instructions of cable and connector manufacturers are to be observed.

Ordering information cable type specification pict. Industrial ethernet ethercat cable shielded pur 1 x 4 x awg26 drag chain suitable cat5 green. Recommended for ethercat communications. Field wireable m12 and rj45 connectors.

For connecting ethercat devices only ethernet cables that meet at least the requirements of category 5 cat5 according to en 50173 or iso iec 11801 should be used. Industrial ethernet ethercat cable shielded pur 4 x 2 x awg26 fixed installation cat7 green. Cable specification with strengthened shield for higher noise resistance. The protocol is standardized in iec 61158 and is suitable for both hard and soft real time computing requirements in automation technology.

It has a stronger resistance to signal interference. Ethercat network 2 2 ethercat interface specification ethercat interface should be connected by twisted pair wire. Ethercat p ethercat power is an addition to the ethercat technology on the cabling level. Murrelektronik has the right connection for every application.

From pvc jackets for fixed cable installations to highly flexible pur cables with a wire cross section. The cable length between two ethercat devices must not exceed 100 m. The screen material must meet the electrical and mechanical requirements. In addition to a double shield structure copper foil tape is added to the m12 connector to improve communication characteristics see below.

It s suitable for up to 10gigabit ethernet at 250 mhz.
