What are IEC Connectors?
Meet the Connector: IEC Connectors
IEC connectors or plugs are a broad category of power connectors for various uses that follow the International Electrotechnical Commission standards.
IEC connectors are not a specific type of connector. Instead, they are a broad category of different types of electronic and electrical power connectors that meet the International Electrotechnical Commission standards (IEC standards). These connectors serve many markets, including Medical, Consumer (white and brown goods), Industrial, Automotive, Transportation, Test & Measurement, and more. Hundreds of interconnect products are tested and standardized by the IEC, as well as capacitors, transformers, cables, sensors, fuses, and other components. IEC connectors are identified by a numerical system indicating the specific relevant standard.

Many other IEC standards are highly relevant to connectors, particularly those that refer to cables and other connector-adjacent technologies. IEC 60038, which standardizes voltages, IEC 61760, which standardizes surface mounting technology, and IEC 60059, which standardizes current ratings are also central to interconnects.
- IEC standards are developed with input from industry and research institutions.
- IEC standards have often been adopted as national or regional standards; close to 80% of European electrical and electronic standards are in fact IEC International Standards.
- The IEC has a clear, strictly controlled standards development process. It governs the development and publication of IEC International Standards and reviews input from stakeholders at different stages of development.
- Testing to support IEC standards are transparent, predictable, comparable, and affordable.
- IEC standards help reduce trade barriers caused by different certification criteria in different countries.
- The IEC is prioritizing energy efficiency through several technical committees, with an emphasis on e-mobility systems, electricity supply infrastructure, self-driving technology, and in-vehicle multimedia systems.
- UL standards largely follow IEC standards.
