IEC 61169-29:2005

Overview

IEC 61169-29:2005 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies sectional requirements for miniature radio-frequency (RF) coaxial connectors. This standard covers connectors with coupling mechanisms such as screw, snap-on, push-pull, quick-lock, and slide-in types designed primarily for rack and panel applications. The connectors discussed in IEC 61169-29 have a characteristic impedance of 50 Ω (type 1.0/2.3), and are applicable to both 50 Ω and 75 Ω systems.

This standard aims to provide comprehensive guidance for the preparation of detailed specifications for RF coaxial connectors used in high-frequency electrical and electronic applications. It ensures compatibility, performance consistency, and reliability in communication and measurement systems where miniature coaxial connectors are essential components.
