Overview

EN 4165-002:2023 is a European standard developed by CEN for the aerospace sector, focusing on rectangular, modular electrical connectors with a continuous operating temperature of 175 °C. This standard defines general conditions, performance specifications, and contact arrangements for receptacles, plugs, and rack-and-panel connectors. The connectors covered are modular and allow for interchangeable modules, ensuring flexibility, reliability, and resistance to harsh aerospace environments.

Key Topics

• Modular Connector Design: The standard covers connectors that use a modular, rectangular configuration, which supports a variety of interchangeable modules. This enables customization for different applications and system requirements in aerospace electrical systems.
• Operating Temperature: All connectors specified by EN 4165-002:2023 are rated for a continuous operating temperature of 175 °C, ensuring performance in demanding conditions.
• Shell Classes and Materials: Various classes based on shell material and surface treatment are defined, including composite materials, cadmium-plated, black nickel-plated, and nickel-plated variants. These classes address requirements for corrosion resistance, salt mist protection, and mechanical durability.
• Electrical and Mechanical Performance:
  • Electrical parameters include insulation resistance (5,000 MΩ at ambient), withstanding voltage, and current-carrying capacities based on contact and cable size.
  • Mechanical performance includes a minimum of 500 mating/unmating cycles, providing longevity in service.
• Contact Arrangements: Detailed configurations for contact layouts are provided for both male and female modules across series 2 and series 3, supporting diverse system architectures.
• Compatibility and Accessory Combinations: The standard specifies permissible combinations of plugs, receptacles, protective covers, accessories, and chimneys to guarantee intermateability and performance within the product family.

Applications

EN 4165-002:2023 connectors are primarily used in:

• Aerospace equipment and systems: These connectors are suitable for installation in aircraft electrical and avionic systems requiring reliable operation under high temperatures and exposure to vibration, fluids, and corrosive environments.
• Defense applications: Modular connectors defined by this standard are used in both military and commercial aerospace vehicles due to their flexibility and robust performance.
• Rack-and-panel installations: The specification includes rack-and-panel connector types, supporting efficient modularity in avionics bays and equipment racks.
• Custom electrical harnesses: Modular contact arrangements make these connectors ideal for customized electrical interconnection solutions where flexibility and upgradeability are important.

Related Standards

EN 4165-002:2023 is part of a comprehensive suite of aerospace connector standards. Related documents include:

• EN 4165-001: Technical specification for the product family, covering general requirements.
• EN 4165-003, EN 4165-004, EN 4165-005: Product standards for specific module types and mounting configurations.
• EN 3155 series: Standards for electrical contacts used within connectors.
• EN 2591-207, EN 2591-209: Methods for electrical and thermal testing, including voltage proof and current derating.
• EN 4529-002: Standards for sealing plugs.
• EN 3197: Guidance on design and installation of aircraft electrical and optical interconnection systems.

For organizations involved in aerospace manufacturing, maintenance, and system integration, compliance with EN 4165-002:2023 ensures compatibility, safety, and sustained performance of electrical connectors in critical applications. Meeting this standard supports reliability, streamlines certification, and promotes system interoperability throughout the aerospace supply chain.
