Overview
EN 4652-321:2017 is a CEN (ASD‑STAN) product standard in the aerospace series that defines the characteristics and tests for 50 Ω coaxial radio‑frequency connectors - specifically the Type 3 N‑interface, crimp assembly version, right‑angle plug. The standard covers mechanical, electrical and environmental requirements for crimped cable‑to‑connector assemblies intended for aerospace use, including configuration, materials, marking, packaging and qualification.
Key topics and technical requirements
- Connector type: Right‑angle plug, screwed‑on coupling (N interface), crimp assembly technology.
- Electrical:
- Characteristic impedance: 50 Ω
- Maximum operating frequency: 6 GHz
- VSWR limits: ≤ 1.10 at 3 GHz, ≤ 1.15 at 6 GHz
- Contact resistance (initial central contact): ≤ 1.5 mΩ
- Insulation resistance: ≥ 5 000 MΩ
- Dielectric withstand: 1 500 V r.m.s. at sea level (with altitude derating table)
- Mechanical:
- Service life: 500 mating cycles
- Retention of centre contact: ≥ 27 N
- Tightening torque of coupling nut: 3.7 m.N (specified in standard)
- Mating/unmating torque and mechanical endurance tests defined
- Environmental & RF testing:
- Defined test program including shock, sinusoidal & random vibration, thermal cycling, salt mist, sand/dust, humidity/low pressure, corona, lightning strike and RF leakage
- RF performance tests: VSWR, insertion loss, characteristic impedance, surface transfer impedance and RF high‑potential tests
- Materials & construction:
- Centre contact: copper alloy with gold over nickel plating; insulators PTFE; seals silicone rubber; allowable heat‑shrink polyolefin ≥135 °C
- Cable/tooling compatibility:
- Accepts specified cable groups (WM, WD, WN) with prescribed crimp tooling (M22520 series) and stripping lengths per TR 6058 / EN 2812
Applications and who uses this standard
- Aerospace and defence OEMs specifying aerospace RF coaxial connectors (N interface) for avionics, communication, radar and telemetry systems.
- Connector manufacturers implementing crimp right‑angle N plugs for 50 Ω cabling.
- Procurement, qualification and quality assurance teams requiring clear acceptance criteria and test methods.
- Test laboratories conducting environmental, mechanical and RF verification for airborne hardware.
- System integrators and harness manufacturers installing crimped RF assemblies to aerospace standards.
