EN 4652-312:2015 - Overview
EN 4652-312:2015 is a CEN aerospace product standard that defines the characteristics and requirements for a Type 3 N interface, clamp nut assembly version, square flange receptacle - a 50 ohm coaxial RF connector intended for aerospace use. The standard covers mechanical, electrical and environmental properties for cable-to-connector assemblies using clamp technology and is part of the Aerospace series of coaxial connector standards.
Key topics and technical requirements
- Interface and impedance: N interface, 50 Ω nominal (connector characteristic impedance 50 Ω ±5 Ω at 200 MHz).
- Electrical performance: Maximum operating frequency up to 6 GHz; VSWR ≤ 1.15 up to 6 GHz; insertion loss specified (see standard for formula); contact resistance and insulation resistance limits (centre contact ≤ 1.5 mΩ initial; insulation ≥ 5 000 MΩ).
- Materials and finishes: centre contact - copper alloy gold plated over nickel; insulators - PTFE; seals - silicone rubber; body - copper alloy nickel plated; heat-shrink - polyolefin.
- Environmental & mechanical: Operating temperature −65 °C to +165 °C; service life 500 cycles; centre contact retention ≥ 27 N; cable retention 180 N (cable groups A and B).
- Tests & qualification: Comprehensive test program referenced to EN 2591 series including contact resistance, VSWR, insertion loss, RF leakage (−50 dB for cable group A, −60 dB for group B between 2–3 GHz), corona, salt mist, vibration, shock, mechanical endurance and pressure/altitude (voltage proof at sea level and reduced pressures).
- Configuration & marking: Mechanical dimensions and mass, square flange mounting, marking, packaging and designation follow EN 4652-001 cross-references.
Practical applications and users
- Who uses this standard: aerospace OEMs, avionics engineers, RF subsystem designers, connector manufacturers, procurement/specification writers and test laboratories.
- Typical applications: aircraft and spacecraft RF links, antennas, telemetry, radio communications and avionics interconnects requiring robust, qualified 50 Ω coaxial interfaces with square flange mounting and clamp nut assembly for cable harnesses.
