Overview
EN IEC 61169-54:2021/prA1:2025 - Amendment 1 updates the sectional specification for radio frequency coaxial connectors with a 10 mm inner diameter of the outer conductor, nominal 50 Ω characteristic impedance, Series 4,3-10 (often written 4.3-10). Issued as a Committee Draft for Vote (CDV) in 2025, this amendment addresses mechanical performance - specifically the coupling torque requirements for screw-type connectors - and replaces the mechanical data portion of Table 8 in IEC 61169-54 Edition 2 (2021).
Key Topics and Requirements
- Scope: Sectional specification for Series 4,3-10 coaxial RF connectors, 10 mm ID outer conductor, 50 Ω.
- Coupling torque (screw type): amended to 5–10 N·m (nominal coupling torque range).
- Proof torque: > 10 N·m (as indicated in the amendment).
- Mechanical limits and forces (selected):
- Centre contact captivation: maximum axial displacement 0.25 mm, axial force 30 N.
- Engagement axial force (typical): 100 N (push/pull).
- Separation axial force (typical): 80 N (push/pull).
- Insertion forces: centre contact ≥ 1.5 N; outer contact ≥ 4 N.
- Cable-fixing mechanical tests: cable rotation (nutation), pulling, bending and torsion are referenced as “See DS” in the amendment (see the standard for detailed test procedures and DS references).
- Rationale: Field reports showed screw-type connections could loosen under tower vibration if torque was limited to 5 N·m; increasing allowable torque to 10 N·m resolved the issue without design changes for manufacturers.
Applications
- Ensures reliable mechanical performance of Series 4,3-10 RF connectors used in:
- Cellular base stations, tower-mounted antennas and feeders
- Microwave radio links and point-to-point backhaul
- Broadcast and telecommunications infrastructure
- Test and measurement fixtures where 50 Ω coaxial interconnects are required
- Helps reduce vibration-related loosening and improves long-term mechanical integrity of screw-type coaxial joints.
Who Should Use This Standard
- RF connector manufacturers and designers
- Test laboratories and conformity assessment bodies
- System integrators, RF installers and telecom operators
- Standards committees and procurement teams specifying connector mechanical performance
Related Standards
- Parent document: IEC/EN 61169-54:2021 (this amendment modifies its mechanical data)
- Other parts of IEC 61169 series cover different connector sizes and types (consult IEC 61169 series for related sectional specifications)
This amendment is intended to stabilize by 2028 and is circulated for parallel IEC–CENELEC voting; consult the final published text for definitive test methods and normative details.
