The bus connectors for CAN are used to connect a CAN network station to the CAN cable. The connector is quickly mounted and has integrated, switchable terminating resistors.

Systeme Helmholz GmbH offers the bus connector with a vertical and axial outgoing cable and for transmission rates up to 1 Mbit/s.


The bus connector is plugged directly onto the CAN bus interface (SUB-D connector, 9-way) of the CAN network stations. The CAN network cables are connected using 6-way screw terminals. Using a slide switch, you can set whether the connector is to be used as a node or segment end. The switch can also be operated when the connector is installed. The setting can be clearly seen. The connector must be operated in node setting ("OFF") when the incoming bus and the outgoing bus are to be interconnected. The terminating resistors are then bypassed. The connector must be set as a segment end ("ON"), on the first and last (extreme) stations of the segment. In that case the terminating resistors are connected on the incoming bus, the outgoing bus is disconnected.
