Overview
EN 4165-027:2015 is a CEN product standard for aerospace rectangular modular electrical connectors, specifically the rack and panel rear mounted plug in series 3 for 2- and 4-module assemblies. The standard covers form, fit and key functional requirements for plugs designed for continuous operation up to 175 °C, and it is part of the EN 4165 family used widely in avionics and aerospace electrical systems.
Key topics and technical requirements
- Scope: Defines the rack-and-panel rear-mounted plug for 2 and 4 modules (series 3). Corresponding receptacles are specified in EN 4165-002; protective covers referenced in prEN 4165-019.
- Operating temperature: Rated for 175 °C continuous operation (consistent with EN 4165 series).
- Mechanical details:
- Dimensional drawings and required characteristics provided (figures for 2-module and 4-module plugs; dimensions in millimetres).
- Screw coupling torque on panel: 0.6 N·m ± 0.1 N·m.
- Material / corrosion classes (Table 1):
- Class W: Aluminium alloy housing, olive-drab cadmium plated, 500 hours salt mist resistance, 175 °C rating.
- Class F: Aluminium alloy housing, black nickel plated, 96 hours salt mist resistance, 175 °C rating.
- Designation & marking:
- Standardized designation format (example: EN4165F9B4R00) covering basic standard number, class, type, series, module count, rear mounting, keying and coupling state.
- Marking to follow EN 2424 (category P) unless otherwise specified.
- Normative references: EN 4165-001 (technical spec), EN 4165-002 (receptacles & contact arrangements), EN 4165-021 (coupling keyway), prEN 4165-019 (protective cover), EN 2424.
Applications and users
EN 4165-027 is intended for:
- Aerospace OEMs and avionics manufacturers specifying rack-and-panel electrical interfaces.
- Connector designers and manufacturers producing rectangular modular connectors for high-temperature environments.
- Procurement specialists and maintenance/repair organizations requiring standardized plugs compatible with EN 4165 receptacles.
- Test engineers and certification bodies validating mechanical, thermal and corrosion performance for aviation systems.
Typical applications include avionics racks, mission-critical control panels, and aircraft electrical distribution where compact modular connectors and high continuous-temperature capability (175 °C) are required.
