Cables and Connectors
Cables and connectors represent critical interfaces in the electromagnetic compatibility of electronic systems. These components bridge the gap between shielded enclosures, providing pathways for signals and power while potentially creating opportunities for electromagnetic interference to enter or exit protected volumes. Proper design and selection of cables and connectors is essential for maintaining system-level EMC performance.
The electromagnetic behavior of cables and connectors depends on their construction, materials, termination methods, and integration into the overall system architecture. Understanding how these elements contribute to both conducted and radiated emissions, as well as immunity to external interference, enables engineers to make informed decisions that balance EMC requirements against cost, size, weight, and reliability constraints.
