Overview
IEC 61076-3-110:2016 is an international standard published by the International Electrotechnical Commission (IEC) that specifies detailed product requirements for free and fixed connectors used in electronic equipment for data transmission at frequencies up to 3000 MHz. It defines mechanical, electrical, and environmental criteria, ensuring compatibility and performance in high-frequency data communication applications.
This standard covers connectors that support individual pairs of contacts, which can be shielded separately within a connector to minimize interference. The connectors specified in IEC 61076-3-110 are designed to be intermateable with the widely used IEC 60603-7 series connectors-common in ISO/IEC 11801 balanced cabling systems-while extending functionality to support higher frequencies and additional features.
The revision consolidates transmission requirements for frequencies up to 3000 MHz, thereby addressing modern high-speed data transmission needs effectively.
Key Topics
-
Mechanical Requirements
The standard specifies the design and physical dimensions of both free (plug) and fixed (socket) connectors to guarantee reliable mating and mechanical robustness over repeated use. This includes cable terminations, mounting interfaces, and pin assignments.
-
Electrical Characteristics
Key electrical parameters addressed include insertion loss, return loss, propagation delay, delay skew, and various forms of crosstalk-near-end crosstalk (NEXT), far-end crosstalk (FEXT), and alien crosstalk (PSANEXT, PSAFEXT). These ensure optimal signal integrity at frequencies up to 3 GHz.
-
Transmission Performance
The specification mandates performance criteria for data transmission up to 3000 MHz, supporting modern high-frequency balanced cabling systems with specific emphasis on performance for separated pairs of contacts, which can be individually shielded.
-
Environmental and Climate Classification
Connectors must meet defined environmental conditions with adherence to climate categories, clearance and creepage distances, and adequate current-carrying capacity under operating conditions.
-
Intermateability and Backward Compatibility
These connectors maintain backward compatibility with IEC 60603-7-7, IEC 60603-7-71, and IEC 60603-7-82 connectors, facilitating smooth integration into existing systems and incremental upgrades.
-
Testing and Quality Assurance
A comprehensive test schedule ensures conformity to mechanical and electrical standards, helping manufacturers and users validate performance, durability, and safety.
