Overview

EN 3155-070:2019 is a CEN product standard in the aerospace series that specifies required characteristics, tests and tooling for male electrical contacts (type A, crimp, class S) used in elements of connection according to EN 3155-002. It is intended to be used together with EN 3155-001 (technical specification) and references associated female contact standards (EN 3155-003, EN 3155-009, EN 3155-071). Class S contacts are for general application with an operating temperature range of −65 °C to +200 °C.

Key topics and technical requirements

  • Scope & designation
    • Covers male, crimp-type A contacts (product standard) and gives designation examples (e.g., CONTACT, ELECTRICAL EN3155-070M2220).
  • Materials & finishes
    • Body material: copper alloy.
    • Surface treatment: gold on appropriate undercoat (thickness per EN 3155-001; selective protection permitted).
  • Dimensions & marking
    • Dimensions and mass specified in millimetres and apply after surface treatment; colour-code marking follows ISO 8843 (examples: size 22/22 = green/green; 22/20 = green/red).
  • Permissible conductors & stripping
    • Accepts common AWG/mm² conductor sizes (e.g., AWG 22, 24, 26, 20 equivalents); nominal stripped length 4 mm ±0.5 mm.
  • Tooling
    • Crimp tooling conforming to SAE-AS22520 (selector positions provided).
    • Insertion/extraction tools conforming to SAE-AS81969.
  • Testing
    • Test program references EN 2591 series and EN 3155-001; includes:
      • Low-level and current contact resistance tests
      • Endurance at temperature: T = (200 ± 2) °C, duration 1 000 h
      • Rapid temperature change cycles between +200 °C and −65 °C
      • Mechanical tests (tensile strength of crimped connection per EN 2242, with AWG 20 min = 70 N)
      • Environmental tests: salt mist, fluid resistance, ozone, etc.

Applications

  • Designed for aerospace and avionics electrical connectors (e.g., EN 4165 modules) where high reliability, high temperature tolerance and standardized crimp terminations are required.
  • Typical use cases: aircraft harness manufacturers, connector suppliers, OEM integration of modular rectangular connectors, avionics repair and maintenance, and environmental/test qualification.

Who should use this standard

  • Connector and contact manufacturers
  • Cable harness designers and assembly shops
  • Aerospace OEMs and suppliers (design, procurement, QA)
  • Test laboratories performing qualification to aerospace connector requirements

Related standards

  • EN 3155-001, EN 3155-002, EN 3155-003, EN 3155-009, EN 3155-071
