Overview
EN 4652-322:2017 is a CEN aerospace product standard for coaxial radio-frequency connectors: Type 3, N interface - crimp version - square flange receptacle. It defines mechanical, electrical and environmental characteristics for 50 Ω N‑interface square flange receptacles used in aerospace cabling assemblies where the cable‑to‑connector termination is by crimp technology.
Key topics and requirements
- Electrical characteristics
- Characteristic impedance: 50 Ω
- Maximum operating frequency: 6 GHz
- VSWR limits (example): ≤ 1.10 at 3 000 MHz, ≤ 1.15 at 6 000 MHz
- Contact resistance (initial central contact): ≤ 1.5 mΩ
- Insulation resistance: ≥ 5 000 MΩ
- Withstand voltage: 1 500 Veff (sea level)
- Mechanical and materials
- Service life: 500 mating cycles
- Tightening torque of coupling nut: specified in standard (see Clause 3)
- Retention of centre contact: ≥ 27 N
- Cable retention: specified per cable group (examples: 140 N or 400 N)
- Materials: centre contact gold plated copper alloy over nickel; PTFE insulators; silicone seals
- Configuration and dimensions
- Square flange receptacle dimensions, mass and marking are defined (see Figure 1 / Table 1).
- Holes for safety/lockwire required where no self‑locking device exists.
- Assembly and tooling
- Acceptable cable groups and crimp tooling are listed (e.g., cable codes WM, WD, WN and M22520-series crimp tools/locators).
- Stripping lengths specified per cable group (see Clauses 3.6.1–3.6.2).
- Qualification and testing
- Extensive test program: low‑level contact resistance, VSWR, insertion loss, RF leakage, corona, environmental tests (thermal cycles, salt mist, sand/dust), shock, vibration, mechanical endurance and crimp tensile tests.
- Qualification references: EN 4652‑001 and EN 9133 for quality/qualification procedures.
Applications and users
- Intended for aerospace RF signal paths where robust, qualified 50 Ω N‑type connections are required:
- Aircraft and spacecraft RF subsystems
- Avionics and antenna interfaces
- Aerospace harness manufacturers and cable assembly shops
- Design, procurement and quality engineers specifying aerospace‑grade RF connectors
- Useful for engineers verifying compatibility, environmental performance, and qualification testing of crimped N‑interface square flange receptacles.
