Overview
EN 4652-220:2017 is a European aerospace product standard that specifies the characteristics for 50 Ω TNC (screwed coupling) straight coaxial plugs - crimp version. Intended for use with lightweight coaxial cables, this standard defines mechanical, electrical and environmental requirements, materials, marking, packaging and test methods specific to aerospace and defence RF connector applications.
Key topics and requirements
- Connector type: TNC interface, straight plug, crimp assembly (Type 2).
- Impedance and RF performance:50 Ω nominal; maximum operating frequency 6 GHz. VSWR limits are specified (e.g., ≤1.10 at 150 MHz, ≤1.15 at 1 200 MHz, ≤1.20 at 6 000 MHz) and insertion loss defined as 0.06·√f dB max. (f in GHz) for the mated connector pair.
- Materials and finishes: center contact - copper alloy gold-plated over nickel; insulators - PTFE; seals - silicone rubber or fluorinated elastomer; body/coupling materials required to suit mechanical/electrical use.
- Environmental and mechanical: operating temperature –65 °C to 165 °C; service life 500 cycles; coupling nut torque and proof torque limits; retention forces for center contact and cable specified. Water ingress resistance required for mated connectors (and for certain cable groups in unmated condition).
- Cable compatibility and assembly: accepts specified lightweight cable groups (codes WM, WZ, WD, WN) with defined stripping dimensions and crimp tooling (e.g., M22520 series tools and dies).
- Testing and quality assurance: references extensive test methods (visual, contact resistance, VSWR, insertion loss, RF leakage, salt mist, immersion at low pressure, vibration, shock, crimp tensile strength, etc.) and mandates application of EN 9133 quality procedures.
Practical applications and users
- Who uses it: aerospace and defence OEMs, subcontractors, RF hardware designers, cable assembly shops, and procurement/specification engineers working on aircraft, space or military equipment requiring qualified RF coaxial connectors.
- Why it matters: ensures interoperability, reliable RF performance and environmental robustness for mission-critical radio-frequency links in airborne systems. It guides selection, crimp assembly, sealing requirements for lightweight coaxial cables and qualification testing to meet aerospace reliability standards.
