EN IEC 61169-54:2021/FprA1:2026 is a CLC amendment to the sectional specification for radio-frequency (RF) coaxial connectors in Series 4,3-10. It updates the mechanical data for connectors with a 10 mm inner diameter of outer conductor and a nominal characteristic impedance of 50 Ω. Engineers, manufacturers, test laboratories and buyers use it when the coupling and mechanical performance of these connectors has to be specified or checked.
What does EN IEC 61169-54:2021/FprA1:2026 specify?
EN IEC 61169-54:2021/FprA1:2026 specifies one amendment to the RF connector sectional specification for coaxial connectors in Series 4,3-10. Its main effect is to change the coupling torque requirement for screw type connectors and to replace the mechanical data in Table 8 of IEC 61169-54 Edition 2 (2021-08).
The amendment is organized as a short front matter, a purpose statement, the replacement mechanical-data table, and a reasoning note. In practice, that means readers use it together with the base part to apply the revised mechanical values.
What are the key requirements of EN IEC 61169-54:2021/FprA1:2026?
The amendment focuses on the mechanical data for the connector interface. The most important point is the revised coupling torque for screw type connectors, because this is the setting that affects how firmly the connector locks in service.
Mechanical strength and coupling
- Clause 9.3.11 updates strength of coupling mechanism for screw type connectors to a coupling torque of 5-10 N m and a proof torque of > 10 N m. In practice, this tells manufacturers and users what tightening behavior the coupling mechanism has to tolerate.
- The reasoning states that limiting coupling torque to 5 N·m led to loosening under tower vibrations, and that 10 N·m solved the problem. In practice, this explains why the torque range matters for outdoor or vibrating installations.
Contact retention and mating forces
- Clause 9.3.5 gives centre contact captivation with a maximum axial displacement of 0,25 mm and an axial force of 30 N. This matters because the centre contact has to stay properly retained during handling and use.
- Clause 9.3.6 gives engagement and separation force for push pull connectors as typically 100 N for engagement and 80 N for separation. In practice, this defines how hard the connector is to mate and unmate.
- Clause 9.3.4 gives insertion force of at least 1,5 N for the centre contact and at least 4 N for the outer contact. This helps confirm that the contact interface can be assembled without excessive force.
Cable-fixing checks
- Clauses 9.3.7 to 9.3.10 point to mechanical tests on cable fixing: cable rotation, cable pulling, cable bending and cable torsion. In practice, these checks are used to verify the connector-cable interface under installation and service stresses.
What terms does EN IEC 61169-54:2021/FprA1:2026 define?
- RF - Radio-frequency, the signal range covered by these connectors.
- Screw type - A connector coupling style tightened by thread engagement.
- Push pull - A coupling style that mates and separates by axial movement.
- Coupling torque - The tightening torque applied to the connector coupling mechanism.
- Proof torque - A higher torque level used to show the coupling can withstand overload without failure.
- Centre contact captivation - The retention of the centre contact against axial movement.
- Insertion force - The force needed to insert the centre or outer contact.
- Series 4,3-10 - The product series named in the standard for this connector family.
Who uses EN IEC 61169-54:2021/FprA1:2026?
EN IEC 61169-54:2021/FprA1:2026 is used by connector manufacturers, test laboratories, design engineers, and quality or purchasing teams that specify RF coaxial connectors. It is especially relevant where screw type connectors may be exposed to vibration, because the torque setting affects field reliability and customer acceptance.
What changed in EN IEC 61169-54:2021/FprA1:2026 from the previous edition?
Compared with IEC 61169-54 Edition 2 (2021-08), Amendment 1 updates the coupling torque requirement for screw type connectors and replaces the mechanical data in Table 8. The reasoning note links the change to field complaints about loosening under tower vibration and to test results showing that 10 N·m addresses the issue.
Which standards are used with EN IEC 61169-54:2021/FprA1:2026?
The amendment is used with IEC 61169-54 Edition 2 (2021-08), which provides the base sectional specification and the Table 8 mechanical data that this amendment replaces.
What does the EN IEC 61169-54:2021/FprA1:2026 document contain?
The document contains a short amendment front matter, the purpose of the amendment, a replacement mechanical-data table, and a reasoning note. The table covers centre contact captivation, engagement and separation force, strength of coupling mechanism, insertion force, and mechanical tests on cable fixing. It is the part readers use for design review, compliance checking and test planning.
