The B&R 7AC Bus Connectors series is a group of CAN bus connectors used to connect nodes to two bus lines in industrial communication networks.
The series is designed to allow a CAN node to be exchanged without interrupting the network connection, which helps simplify service work on an active system. It also includes switchable 120 Ω terminating resistance so the end-of-line termination can be adjusted quickly when the network structure changes. The connector design includes built-in stress relief to support more secure cable handling in the installation. Overall, the 7AC series is intended for CAN network connections where maintainability, simple termination handling, and stable physical bus wiring are required.
