B&R Industrial Automation 7AC911.9 CAN Network Bus Controller

The 7AC911.9 is a CAN bus connector from B&R's 7AC infrastructure family, designed to connect a controller to a CAN network with an integrated termination resistor. Configured with a 9-pin female DSUB interface, it supports two CAN bus lines via screw-clamp terminal blocks and provides integrated strain relief for robust, industrial-grade cabling. The terminating resistor is switchable, enabling termination at the ends of the CAN run to suppress reflections, and the unit carries CE and UKCA markings for compliance with European and UK standards. CAD data are available in DXF/STEP formats for mechanical integration, making it straightforward to incorporate the 7AC911.9 into panel layouts and enclosures.
