IEC 61169-24:2019

Overview

IEC 61169-24:2019 is the sectional specification for radio‑frequency coaxial connectors with screw coupling (type F), typically used in 75 Ω cable networks. This third edition (2019) replaces the 2009 edition and updates interface drawings and gauging to support frequency extension up to 3 GHz. The document provides rules for preparing Detail Specifications (DS), defines interface dimensions and mechanical gauging, and identifies mandatory tests selected from IEC 61169-1.

Key technical topics and requirements

• Interface dimensions and gauging: Precise mechanical drawings, reference planes and gauges for both female (socket) and male (plug) type‑F connectors to ensure interchangeability and reliable mating.
• Center conductor guidance: Gauging and tests for the center conductor acceptance and electrical contact checks to guarantee proper signal continuity.
• Mandatory tests: Selection of required tests from IEC 61169-1 (generic RF connector requirements), including acceptance and periodic test schedules and inspection criteria.
• Quality assessment procedures: Rules for quality conformance inspection, qualification approval and maintenance, and recommended test sequences.
• Performance and ratings: Recommended electrical and mechanical characteristics to consider when drafting a DS (ratings, thread length, contact depths, etc.).
• Environmental considerations: Special requirements and environmental characteristics for outdoor sockets (Annex A) and satellite broadcasting variants (Annex B).
• Documentation aids: Instructions and a blank DS pro‑forma to help manufacturers and spec writers prepare compliant detail specifications.

Practical applications

IEC 61169-24 is used wherever type‑F connectors are specified, including:

• Cable TV and broadband distribution (set‑top boxes, wall sockets, amplifiers)
• Satellite and broadcast receiving equipment (satellite F variants covered in Annex B)
• Cable modems, routers and consumer RF devices using 75 Ω coax
• Outdoor equipment and weather‑protected sockets (Annex A guidance)

Who should use this standard

• Connector designers and manufacturers preparing products and detail specifications (DS)
• Quality and compliance engineers performing acceptance, periodic and qualification tests
• Test laboratories and certification bodies applying IEC 61169‑1 test methods to type‑F connectors
• Procurement and specification writers in broadcast, telecom and cable industries
