Overview

SIST EN 4652-210:2016 is a European Standard developed by CEN under the Aerospace and Defence Industries Association of Europe (ASD-STAN). It specifies the product requirements for aerospace-grade coaxial connectors, specifically the straight plug version of 50-ohm connectors with a threaded TNC interface and clamp nut assembly. These connectors are designed for radio frequency applications within aerospace systems, ensuring reliable electrical performance and mechanical durability under demanding environmental conditions.

This standard addresses the characteristics, design, material specifications, electrical and mechanical performance, test procedures, and quality assurance measures for these TNC interface coaxial connectors. It is essential for manufacturers and quality engineers in the aerospace sector aiming to comply with industry requirements for high-frequency coaxial connector assemblies.

Key Topics

• Connector Configuration and Materials
  The standard defines precise dimensions, mass limits, and assembly style for straight plug TNC connectors using clamp nut technology.
  Key materials include copper alloy with gold plating for contacts, PTFE insulators, silicone rubber seals, and nickel-plated copper alloy bodies to offer excellent electrical conductivity and environmental resistance.

• Electrical Characteristics

  • Characteristic impedance: 50 Ω
  • Maximum operating frequency up to 6 GHz
  • Voltage standing wave ratio (VSWR) not exceeding 1.15 up to 6 GHz
  • Insertion loss specified as 0.04f dB maximum (f in GHz)
  • Contact resistance less than 1.5 mΩ initially on center contacts
  • High insulation resistance and withstand voltage capacity for reliable RF performance

• Environmental and Mechanical Performance
  These connectors are designed to operate between -65 °C and +165 °C, with water ingress resistance both mated and unmated for specified cable groups. They comply with rigorous tests including salt mist exposure, vibration, shock, temperature cycling, dust and sand resistance, low air pressure, and fluid resistance ensuring durability in aerospace conditions.

• Test Methods and Qualification
  The standard mandates comprehensive testing protocols based on aerospace series test methods (EN 2591 series). Tests cover mechanical endurance, electrical resistance, RF leakage, corona discharge, plating quality, and more to validate compliance before product qualification and production.

• Quality Assurance and Marking
  Manufacturers must implement quality systems meeting EN 9133. Products require clear marking according to aerospace connector identification conventions for traceability and standardized packaging and storage procedures for preservation.

Applications

• Aerospace and defense communication systems relying on high-frequency, low-loss RF signal transmission
• Avionics equipment requiring rugged, vibration-resistant coaxial connections
• Satellite and spaceborne telemetry systems where temperature extremes and environmental exposure are critical
• Military radio frequency devices demanding secure, self-locking connectors with clamp nut assembly technology
• High-reliability testing and instrumentation cables in aerospace manufacturing and maintenance

These connectors enable mission-critical performance in electrically noisy and physically challenging aerospace environments, promoting system integrity and signal quality.
