Overview
EN 3155-044:2019 is a CEN product standard in the Aerospace series that defines the required characteristics, marking and tests for electrical male contacts (male 044, type A, double crimping, class T) used in aerospace connector elements. It specifies dimensions, materials, plating, permissible cable sizes, tooling and an extensive test regime to ensure reliable performance in aviation and space applications. This standard is intended to be used together with EN 3155-001 (technical specification) and referenced against EN 3155-002 (contact list/utilisation). The mating female contact is defined in EN 3155-045.
Key topics and requirements
- Contact identification and dimensions: Defines dimensional limits, mass and manufacturer marking requirements (manufacturer symbol in non-active area). Contact sizes covered include the common sizes 20 and 22.
- Materials & plating: Body made of copper alloy with selective protection permitted. Minimum gold plating thickness specified (initial gold ≥ 1.27 µm with nickel undercoat; after tests ≥ 0.2 µm).
- Double crimping: Crimp style, crimp geometry and crimp acceptance criteria are specified for reliable mechanical and electrical joints.
- Cable compatibility & stripping: Permissible conductor sizes and recommended stripped cable lengths are given; conductor specs referenced to EN 2083 and EN 4434.
- Tooling & installation: Requires conformance to SAE-AS22520 (crimping tools) and SAE-AS81969 (insertion/removal tools). Tool selector numbers and crimping positions are referenced.
- Colour marking: Band/dot color coding for quick identification (bands and white dot conventions).
- Qualification & tests: Comprehensive test matrix referencing EN 2591 series and EN 3155-001, including contact resistance (low and at rated current), endurance at elevated temperature (e.g., cycles including 260 °C), vibration, shock, salt mist, fluid/ozone resistance, contact/coating thickness and adhesion, and mechanical tests (tensile, bending, insertion/extraction forces).
Practical applications
- Use in aerospace electrical connectors for airborne platforms (aircraft, rotorcraft, satellites) where high reliability, temperature resistance and secure crimped terminations are required.
- Suitable for connector manufacturers, harness assembly suppliers, OEM design engineers, and test laboratories specifying or verifying male 044 type A contacts for aerospace harnesses and systems.
- Applied where components must meet defined environmental tests (high temperature, vibration, shock, salt mist) and electrical performance (low contact resistance, reliable current carrying).
Who should use this standard
- Connector and contact manufacturers
- Cable harness designers and assemblers in aerospace
- Quality and qualification test labs
- Procurement and compliance engineers specifying aerospace connector parts
