IEC 61169-51:2015

IEC 61169-51:2015 defines the sectional specification for RF coaxial connectors with an inner diameter of outer conductors of 13,5 mm, bayonet lock coupling, and a characteristic impedance of 50 Ω (type QLI). For engineering, procurement, and compliance teams, it provides a focused technical reference for connector selection, product evaluation, and documented verification activities. IEC 61169-51:2015 is especially relevant where consistent interface definition, mating reliability, and alignment with RF design requirements are important in technical review and conformity assessment workflows.

IEC 61169-51:2015 standard overview

This document belongs to the IEC 61169 series for radio-frequency connectors and addresses a specific connector family identified as type QLI. Its scope is centered on the sectional specification for RF coaxial connectors using a 13,5 mm outer conductor inner diameter and bayonet lock mechanism at 50 Ω impedance. In practice, it is used as an engineering specification to support product definition, supplier comparison, and technical validation of connector-related characteristics during quality workflows and compliance preparation.

Applications of IEC 61169-51:2015

The document is typically relevant in RF equipment design, connector procurement, laboratory evaluation, and technical documentation for systems that rely on controlled coaxial interfaces. It may support assessment of connectors used in communications hardware, test setups, and other electrical equipment where repeatable mating and impedance consistency are important. Organizations involved in product qualification, conformity assessment, or maintenance documentation often use it to align internal testing workflows with a clearly defined connector reference.

Why IEC 61169-51:2015 matters

Using a clear connector specification helps reduce interface mismatch, supports operational consistency, and improves confidence during engineering validation. For procurement and compliance teams, it provides a structured basis for documented evaluation of product suitability and supplier claims. In testing and technical review processes, it can help improve comparability between samples and reduce ambiguity in verification activities. That makes it useful for risk management, quality assurance, and preparation of technical compliance evidence.
