Beckhoff EK1122 2-port EtherCAT junction

Weight: 1.000 lbs
1 in stock
Or use

The EK1122 2-port EtherCAT junction can be used in an EtherCAT Terminal segment at any desired position between the EtherCAT Terminals and enables configuration of EtherCAT star topologies. A modular EtherCAT star hub can be realized by using several EK1122 units in a station.

Special features:

  • Connection technology: 2 x RJ45 sockets
  • Connection lengths: up to 100 m
  • Can be used for configuring an EtherCAT star topology

The EK1122 has two RJ45 sockets, which enable connection of an Ethernet cable with RJ45 connector and establish a connection to a further EtherCAT segment or to individual EtherCAT devices. The EK1122 supports coupling and uncoupling of EtherCAT segments during operation (Hot Connect).
