Overview

EN 3545-005:2026 is a CEN standard developed as part of the Aerospace series, specifying the female coding and attachment system for mounting on free housing (plug) within rectangular electrical connectors. These connectors are designed with both sealed and non-sealed rear plastic housings and integrated locking devices, supporting operating temperatures from -55°C to 175°C. This standard details the product requirements for aerospace applications, ensuring quality, interoperability, and reliable performance in harsh environments.

This standard supersedes EN 3545-005:2014, providing updated requirements for materials and surface treatments, as well as clarifying designation and technical characteristics.

Key Topics

• Female Coding and Attachment Systems: Defining the structure, coding, and secure attachment method for female components used in free housing (plug) connectors.
• Material and Surface Treatments: Specification of the materials (such as cadmium-plated steel, zinc/nickel alloys with trivalent passivation) for key components like the body, retaining ring, washer, and captive screw, ensuring corrosion resistance and durability. Mixing surface treatments on a single attachment and coding system is not allowed.
• Dimensional and Mechanical Features: Maximum mass (3 g), exact dimensions and tolerances, and details for elements such as knurling, retaining rings, captive screws, and position indicators.
• Environmental Performance: Ensuring connector systems are robust across an operating temperature range of -55°C to 175°C, suitable for demanding aerospace conditions.
• Locking and Security: Includes a locking screw with a specified tightening torque range for secure attachment and reliable in-service operation.

Applications

This standard is essential for organizations involved in the design, assembly, and maintenance of electrical systems for aerospace and aviation, offering practical guidance on selecting and implementing connector systems with consistent performance. Key applications include:

• Aerospace Electric Equipment: Used in fixed-wing and rotary-wing aircraft, satellites, and spacecraft requiring reliable electrical interconnections under extreme environmental conditions.
• Aviation Connector Systems: For systems demanding both sealed and non-sealed solutions, providing flexibility in addressing various pressure, moisture, and chemical resistance requirements.
• Military and Defense Projects: Application in mission-critical defense electronics where standardized, robust electrical connectors are essential for operational security and continuity.
• High-Performance Industrial Uses: Applicable in industrial segments where exposure to vibration, temperature fluctuations, and demanding operational cycles necessitate aerospace-grade connectors.

The specification aids manufacturers by ensuring interchangeability, compatibility, and safety, streamlining assembly and maintenance practices.
