Overview

SIST EN 3155-031:2009 is a European standard published by the Committee for European Normalization (CEN), defining the product requirements for female electrical coaxial contacts, shielded, size 12, type D, crimp, class R, used in aerospace applications. This standard is part of the aerospace series relating to electrical contacts employed in connection elements, specifically designed to ensure reliability, uniformity, and compatibility in electrical systems used in aerospace environments.

The standard complements EN 3155-001 (technical specification) and EN 3155-002 (list and utilization of contacts). Male contacts compatible with this standard are described in EN 3155-030 and EN 3155-040.

Key Topics

  • Scope and Application
    Establishes requirements for female coaxial electrical contacts with shielding features suitable for aerospace connectors, targeting high reliability in temperature ranges from -65 °C to +150 °C (Class R).

  • Design and Dimensions
    Contacts are size 12, type D, with precise dimensional tolerance in millimeters after surface treatment, ensuring interchangeability and compatibility within the aerospace connector system.

  • Materials and Surface Treatment

    • Outer body and centre contact: Copper alloy
    • Crimp ferrule: Copper alloy
    • Surface treatment: Gold plating over an appropriate undercoat for corrosion resistance and electrical performance
    • Hood: Stainless steel
    • Dielectric: PTFE or equivalent
  • Permissible Cables and Wiring
    Specifies cable groups and codes with dimensional requirements according to aerospace cable coding standards (TR 6058). Crimping and assembly instructions for cable preparation and termination ensure correct installation.

  • Tooling and Assembly
    Details crimping tooling conforming to MIL-DTL-22520 with specific positioners and selectors for different cable groups. Also includes insertion/extraction tools complying with MIL-I-81969/14-04.

  • Testing and Quality Assurance
    Comprehensive testing protocol covers:

    • Visual and dimensional inspection
    • Electrical contact resistance at various currents and temperatures
    • Insulation resistance and voltage proof tests
    • Mechanical endurance including shock, vibration, tensile strength of crimped connections
    • Environmental tests: salt mist, mould growth, fluid resistance
    • Magnetic properties and coating adhesion
  • Marking and Packaging
    Contacts must be individually packaged, labeled with the manufacturer’s name, standard designation, reference, and manufacturing date code to guarantee traceability and protection during transport.

Applications

This standard is essential for aerospace manufacturers, system integrators, and maintenance providers who require high-quality, shielded coaxial female contacts for critical electrical systems in aircraft and spacecraft. The contacts are used in:

  • Avionics and communication systems
  • Radar and navigation equipment
  • Electrical and optical connection elements in aerospace vehicles
  • Equipment requiring resistance to extreme temperatures and environmental conditions

By adhering to SIST EN 3155-031:2009, industry stakeholders ensure interoperability, safety, and durability in demanding aerospace environments.
