Overview

SIST EN 3545-005:2026 is a product standard within the aerospace series that defines requirements for the female coding and attachment system used in rectangular electrical connectors. These connectors feature sealed or non-sealed rears, plastic housings, and an integrated locking device. Operating reliably in a wide temperature range of -55°C to 175°C, this standard focuses specifically on the systems for mounting female components onto free housing (plug) connectors.

Complying with this standard ensures the consistent performance, compatibility, and safety of electrical connectors designed for demanding aerospace environments. The requirements are established to meet the rigorous needs of modern avionics, supporting both current and future aviation electrical system designs.

Key Topics

• Female Coding and Attachment System
  Defines the interface, coding mechanisms, and securement processes for female connectors in free housing (plug) assemblies.

• Environmental Performance
  Specifies suitability across a broad operating temperature range -55°C to 175°C, supporting reliable function in extreme aerospace environments.

• Material and Surface Treatment
  Outlines material requirements (such as steel and beryllium copper) and accepted protective finishes (cadmium or zinc/nickel plating with trivalent passivation). Ensures resistance to corrosion and mechanical wear, with consistent surface treatment across each device.

• Mechanical Dimensions and Mass
  Establishes dimensional tolerances and a maximum allowable mass to ensure interchangeability and minimize weight-a critical consideration in aerospace applications.

• Locking Devices and Torque
  Specifies the locking mechanism and tightening torque, contributing to vibration resistance and secure connector mating.

• Reference to Normative Documents
  Integrates requirements from supporting standards (such as EN 3545-001 and EN 3545-002) for technical specification and performance arrangements.

Applications

The guidance in SIST EN 3545-005:2026 is mainly intended for:

• Aerospace Wiring Systems:
  Incorporation of electrical connectors in aircraft wiring harnesses, avionics modules, and control systems.

• Free Housing Assemblies:
  Design and assembly of plug connectors where female coding and secure attachment are critical for modular installations.

• Sealed and Non-Sealed Electrical Interfaces:
  Solutions for both hermetically sealed systems and conventional open rear arrangements, increasing flexibility in application.

• High-Reliability Environments:
  Use in commercial and military aircraft, ensuring connectors maintain performance under thermal, mechanical, and vibrational stresses.

Complying with SIST EN 3545-005:2026 supports manufacturers and suppliers in delivering high-quality, compatible electrical connectors throughout the lifecycle of aerospace systems.

Related Standards

Understanding and implementing SIST EN 3545-005:2026 is enhanced when used alongside these related documents:

• EN 3545-001: Aerospace Series - Connectors, Electrical, Rectangular, Part 001: Technical Specification
  Establishes general technical requirements for this family of connectors.

• EN 3545-002: Aerospace Series - Connectors, Electrical, Rectangular, Part 002: Specification of Performance and Contact Arrangements
  Defines performance criteria and pin layouts for various connector configurations.

• FED-STD-H28: Screw Thread Standards for Federal Services
  Provides the reference for thread dimensions used in the connector's assembly.

These standards collectively assure integrated system compatibility, safety, and reliability in aerospace electrical equipment and systems.
