Overview

SIST EN 4165-008:2025 is a European standard published by CEN that defines the requirements for aerospace electrical connectors, specifically rack and panel plugs for 2 and 4 modular units, series 2. These rectangular, modular connectors are designed to operate continuously at temperatures up to 175 °C, making them suitable for demanding aerospace environments. This product standard complements the related receptacles and accessories specified in EN 4165-002 and forms part of the broader EN 4165 series dedicated to high-temperature aerospace electrical connectors.

Key Topics

• Scope and Application
  SIST EN 4165-008:2025 specifies the mechanical and marking requirements for rack and panel plugs with 2 or 4 modules in series 2, designed for applications up to 175 °C continuous operating temperature.
• Design and Dimensions
  The standard provides detailed dimensions and maximum mass limits for 2-module plugs (max 38.4 g) and 4-module plugs (max 43.9 g), ensuring interchangeability and consistent performance across implementations.
• Plug Classes
  The plugs are classified into types W and F, offering variations suitable for different connection configurations and operational needs within aerospace systems.
• Marking Requirements
  To ensure full traceability and manufacturing quality, plugs must be marked with a specific identity block, date of manufacture (year-week format), and the manufacturer's name or trademark.
• Technical Specifications
  The connectors conform to the broader technical specifications set out in EN 4165-001, including electrical, mechanical, and environmental performance characteristics.
• Normative References
  The standard references related documents including EN 4165-001, EN 4165-002 (performance and contact arrangements), and EN 4165-021 (coupling system keyway standard), establishing a comprehensive specification framework.

Applications

SIST EN 4165-008:2025 connectors are essential components in aerospace electrical systems requiring reliable high-temperature performance. Typical applications include:

• Aircraft Electrical Wiring
  Integration into control systems where temperature exposure can reach 175 °C continuously, particularly in engine compartments or environmental control systems.
• Spacecraft and Satellite Systems
  High-performance modular connectors ensuring secure signal and power connections in harsh thermal conditions of space missions.
• Military and Defense Aerospace Systems
  Ruggedized plug solutions for avionics installations where standardized modular designs simplify maintenance and replacement.
• Industrial High-Temperature Electrical Installations
  Use in ground support or test equipment interfacing with aerospace hardware under elevated temperature conditions.

By following SIST EN 4165-008:2025, manufacturers and engineers ensure compatibility, safety, and durability of connectors critical to mission success in aerospace applications.

Related Standards

• EN 4165-001 – Technical specifications for aerospace series rectangular modular electrical connectors with 175 °C operating temperature.
• EN 4165-002 – Defines receptacles and accessories compatible with the plugs covered in EN 4165-008.
• EN 4165-021 – Specifies coupling system keyways for plugs, providing standardization on plug engagement mechanisms.

These standards collectively establish a robust framework for high-temperature aerospace electrical connector solutions, facilitating interoperability and quality assurance across aerospace manufacturers and suppliers.
