3.3 CONNECTION CABLES

Ethernet patch or crossover FTP or SFTP cables in CAT5e quality can be used as the connection cables. Lengths of 0.15

to 100 m are permitted for an EtherCAT network.

If you want to make the cables yourself, be sure to select a suitable crimp tool. Afterwards check the quality with a

cable tester to avoid transmission problems.

CAT.5e cables are available with a wire of:

26AWG (wire diameter 0.140mm

, with a resistance of 137 Ohm/km).

24AWG (wire diameter 0.205mm

, with a resistance of 86 Ohm/km).

3.4 ETHERCAT CONNECTION

The Bronkhorst instruments are equipped with a linear bus structure with two RJ45 connectors. The EtherCAT master

is connected (via EtherCAT slaves, if necessary) with a shielded, twisted pair, cable to “EtherCAT IN” (RJ45). Other

EtherCAT instruments are connected via “EtherCAT OUT” (RJ45).

According to IEC 802.3 the maximum cable length for 100 MBaud Ethernet is 100m (100BaseT), e.g.

between two instruments.
