Overview

EN 4165-002:2023 is a CEN European standard specifying performance and contact arrangements for rectangular, modular electrical connectors used in aerospace applications. It applies to plugs, receptacles and rack-and-panel connectors with interchangeable modules (series 2 and series 3) rated for a continuous operating temperature of 175 °C. The document defines common conditions, material classes, intermountability rules and performance requirements for high-temperature aerospace connectors.

Key topics and technical requirements

• Scope and applicability: Covers modular rectangular connectors (plugs, receptacles, rack & panel) with interchangeable modules at 175 °C continuous.
• Contact arrangements: Defines permitted module contact layouts for series 2 and series 3 modules; non-developed layouts withdrawn in this edition.
• Material / shell classes: Codifies shell/material classes (C, W, F, J, M, B) with details on composite or aluminium shells, plating (olive drab cadmium, black nickel, nickel) and salt mist resistance (e.g., 500 h, 96 h, 48 h).
• Operating characteristics: Requirements for electrical, climatic and mechanical performance; includes permissible cables, maximum currents, and derating references.
• Intermountability and accessories: Guidance and synoptic tables (Annex A and B) for plug/receptacle compatibility, protective covers, chimneys, rear accessories and tooling contacts.
• Sealing and rear accessories: Specifications for sealing plugs, chimneys and rear-mounted accessories to maintain environmental sealing at high temperatures.
• Normative references: Cross-references to related EN standards for contact types, test methods (voltage proof, current temperature derating), module and product standards (EN 4165 series).

Practical applications and users

EN 4165-002:2023 is intended for anyone involved in the design, manufacture, procurement and certification of aerospace interconnect systems:

• Aerospace electrical and avionics engineers specifying high-temperature connectors for engine bays, environmental control systems and avionics racks.
• Connector manufacturers producing modular rectangular aerospace connectors to meet standard performance, contact layouts and material classes.
• Systems integrators and maintenance teams ensuring intermountability and correct accessory selection (protective covers, chimneys, sealing plugs).
• Procurement and certification authorities requiring standardized performance and compatibility across suppliers.

Use cases include high-temperature aircraft installations, rack-and-panel assemblies, modular avionics interconnects and corrosive/sea-exposed environments where salt-mist resistance and interchangeability are critical.

Related standards

Relevant documents in the EN 4165 family and referenced product/test standards include:

• EN 4165-001 (Technical specification)
• EN 4165-003 to EN 4165-018 (module, plug, receptacle and accessory product standards)
• EN 2591-207 / EN 2591-209 (test methods)
• EN 3155-082 (contacts) Refer to the standard text and Annexes A/B for synoptic compatibility tables and full performance details.
