The EJ1321 1-port EtherCAT P junction offers the option of converting from an EtherCAT segment to EtherCAT P or extending an EtherCAT P network in line topology.
Special features:
- connection technology: 1 x P-coded M8 socket, external design for direct mounting on the signal distribution board
- conversion from EtherCAT to EtherCAT P
- extension of an EtherCAT P network in line topology
The P-coded M8 socket, which allows an EtherCAT P cable to be connected with an M8 connector, can be used to establish a connection to another EtherCAT P segment or to individual EtherCAT P devices.
