EK1122 – BECKHOFF

EK1122 | 2-port EtherCAT junction
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).
