Overview

EN 3155-047:2007 is a CEN (Aerospace series) product standard that defines the characteristics, tests and tooling for female electrical contacts - type A, double crimping, class S used in aerospace connection elements (per EN 3155-002). It is intended to be used together with EN 3155-001 (technical specification); the matching male contact is specified in EN 3155-046. The standard is primarily applicable to manufacturers, test laboratories and procurement teams for aerospace electrical connectors.

Key topics and requirements

  • Contact construction and materials
    • Body material: copper alloy.
    • Protective plating: selective protection not permitted; minimum gold thickness 1.27 µm over a nickel undercoat.
  • Dimensions and tolerances
    • Detailed dimensional data and mass limits are provided (see Figure/Table references in the standard). Contact and barrel sizes use AECMA sizing codes (examples: size 20, 22).
  • Permissible cables and stripping
    • Acceptable conductor sizes and insulation diameters are specified (e.g., AWG 22 / ~0.4 mm²). Stripped length for the barrel is defined (±0.3 mm).
  • Tooling and insertion/extraction
    • Crimping and insertion/removal tooling must conform to MIL-DTL-22520 and MIL-I-81969 (specific tool and positioner codes are referenced).
  • Testing and qualification
    • A comprehensive test matrix (referencing EN 2591 series) covers:
      • Contact resistance (low-level and at rated current)
      • Insulation resistance and dielectric (voltage proof)
      • Environmental endurance (temperature, rapid temperature change, salt mist)
      • Mechanical tests (tensile, bending, gauge insertion/extraction forces)
      • Electrical performance (discontinuities, capacitance, shielding effectiveness)
    • Example environmental requirement: endurance at temperature T = (200 ± 2) °C for 1 000 h.
  • Designation and marking
    • Recommended designation format (e.g., EN3155-047F2022) and reference to EN 3155-001 for marking rules.

Applications

  • Use in aerospace electrical harnesses and connector systems where reliable, high-reliability female crimp contacts are required.
  • Relevant for:
    • Aerospace connector manufacturers and component suppliers
    • Quality, test and qualification laboratories performing acceptance and environmental tests
    • OEMs, MRO providers and procurement teams specifying connector performance and compatibility
    • Tooling suppliers and harness assembly facilities requiring approved crimping/insertion tools

Related standards

  • EN 3155-001 - Technical specification (must be used together)
  • EN 3155-002 - List and utilization of contacts
  • EN 3155-046 - Male counterpart (type A, double crimping, class S)
  • EN 2591 series - Test methods referenced
  • MIL-DTL-22520 / MIL-I-81969 - Tooling specifications referenced

Keywords: EN 3155-047:2007, female electrical contacts, aerospace connectors, double crimping, type A, class S, crimping tools, contact resistance, protective plating, connector testing.
