Nearly all modern automobiles have a CAN bus network to communicate information around the vehicle from different electronic control units. CAN bus systems have become the backbone of automotive and industrial control systems; offering reliability, efficiency, and ease. However, the CAN bus requires high-quality wiring, and the correct placement of termination, in order to operate properly and avoid signalling issues.

Control Technology offers a comprehensive range of CAN bus interfaces and monitoring software to smoothly transmit data and facilitate connectivity between these units. Terminal resistors play a crucial role and must be placed in these CAN bus systems to prevent signal rebounds and provide cleaner signals. This needs to be done by placing the terminal resistors at each end of the CAN bus; this way, the signal is guaranteed not to be reflected from the cable end, which ensures less interference and error messages.

Our Control Technology terminator resistors offer complete compatibility with all of our CAN bus accessories, complying with the Cia303-1 standard and ensuring ease of installation. Our terminators have been designed by leading manufacturers (CSS Electronics) using a compact structure with a D-sub 9 pin male connector and female socket. The resistance value of our terminators has been measured using the characteristic impedance of a standard CAN bus signal. All terminator resistors have been crafted to allow you to avoid signal distortion and potential data corruption. The resistors act as electrical shock absorbers, and if they are not fitted correctly can cause noisy reflections and significantly affect the performance of the CAN bus communication.
