IEC 61169-4:2008

IEC 61169-4:2008 defines requirements for radio-frequency connectors with an inner diameter of outer conductor of 16 mm and screw lock coupling, using a characteristic impedance of 50 Ω, known as type 7-16. It is relevant where stable RF interconnection, repeatable mating, and documented technical compliance are needed in engineering and procurement workflows. As a primary technical reference, IEC 61169-4:2008 helps teams align connector selection, evaluation, and verification activities for systems that depend on controlled impedance and reliable connection performance.

What is IEC 61169-4:2008?

This document specifies the connector family identified as type 7-16, focusing on RF coaxial connectors with a 16 mm outer conductor interface and screw lock arrangement. In practice, it serves as an engineering specification for organizations that need a consistent compliance reference during product development, laboratory evaluation, or supplier review. It is especially useful when technical documentation must support interoperability, conformity assessment, and controlled comparison of connector designs against a defined interface.

Applications of IEC 61169-4:2008

IEC 61169-4:2008 is typically used in RF equipment programs where robust coaxial connections are required and interface consistency matters. It may support specification work for telecommunications hardware, broadcast-related installations, test setups, and other systems using 50 Ω RF connectors. Procurement teams and laboratories often rely on it during product evaluation, incoming inspection, and technical validation to confirm that connector interfaces match the intended design and installation requirements.

Why is IEC 61169-4:2008 important?

The value of IEC 61169-4:2008 lies in reducing interface ambiguity during design, sourcing, and verification. A clear connector reference supports testing consistency, quality assurance, and risk management by giving engineering and compliance teams a common basis for review. It can also help prepare technical documentation for conformity assessment and regulatory preparation, particularly where dependable RF connections affect operational consistency, system performance, or the reliability of downstream electrical equipment.
