Overview
oSIST prEN 4165-027:2023 is a draft standard developed by the Slovenski inštitut za standardizacijo (SIST), under the CEN framework, for the aerospace industry. This document is part of the European aerospace connector series and specifies the requirements for rear mounted rack and panel plugs for 2- and 4-module configurations, series 3. These modular, rectangular electrical connectors are designed for continuous operation at temperatures up to 175 °C, making them ideal for demanding aerospace environments where reliability, modularity, and thermal performance are critical.
This specific part of the standard supersedes previous editions (EN 4165-027:2015 and SIST EN 4165-027:2016) and works in conjunction with EN 4165-002, which covers the corresponding receptacle connectors.
Key Topics
Rear Mounted Plug Design
The standard focuses on rear mounted rack and panel plugs in 2- and 4-module variants (series 3), ensuring compatibility within the modular EN 4165 connector family.Operating Temperature
Plugs are designed for continuous operation at 175 °C, fulfilling demanding aerospace application requirements.Material and Plating Options
- Class W: Olive drab cadmium plated aluminium alloy, providing 500 hours salt mist resistance.
- Class F: Black nickel plated aluminium alloy, offering 96 hours salt mist resistance.
Technical Specifications
The plugs must comply with detailed technical and marking requirements as provided in EN 4165-001, enhancing traceability and standardization.Compatibility
The plug interfaces directly with receptacles defined in EN 4165-002, promoting system interoperability and modular integration.
Applications
oSIST prEN 4165-027:2023 is essential for aerospace sectors requiring high-performance, modular electrical connectors. Typical applications include:
Avionics Systems
Used for reliable, high-density electrical interconnections within aircraft avionics bays, ensuring secure signal and power distribution.Aircraft Instruments and Control Panels
Supports rear-panel mounting, simplifying maintenance and module replacement without disturbing front-end assemblies.Modular Aerospace Assemblies
Enables flexible reconfiguration or expansion of electronic systems in both commercial and military aircraft.Systems Operating in Harsh Environments
Ideal for environments exposed to high temperatures, vibration, and corrosive atmospheres, notably due to enhanced plating options.
By adhering to these standardized connectors, manufacturers and system integrators enhance the safety, interchangeability, and serviceability of aerospace equipment.
