Overview

EN 3545-003:2005 is a European Standard developed by the European Committee for Standardization (CEN) under the Aerospace series for electrical connectors. This part 003 of the series specifies rectangular electrical connectors with female contacts, featuring plastic housings with sealed and non-sealed rear options. These connectors include locking devices and are designed to operate in extreme temperature conditions ranging from -55 °C to 175 °C.

The standard defines the physical, functional, and performance characteristics necessary for aerospace-grade connectors used in both fixed housings (receptacles) and free housings (plugs). It also incorporates the relevant coding and attachment systems required to ensure secure mechanical and electrical connections.

Key Topics

• Connector Design and Construction

  • Rectangular electrical connectors with plastic housings
  • Sealed and non-sealed rear options for environmental protection
  • Locking devices for secure connections
  • Female contacts compatible with aerospace applications

• Operating Conditions

  • Operating temperature range from -55 °C to 175 °C
  • Suitable for harsh aerospace environments with rigorous thermal and mechanical demands

• Coding and Attachment Systems

  • Connectors use a coding system to prevent mismating
  • Male coding and attachment for mounting on fixed housings (receptacles)
  • Female coding and attachment for mounting on free housings (plugs)

• Dimensional and Technical Specifications

  • Detailed dimensions and mass specifications (max 19 g for non-sealed and 21 g for sealed housing)
  • Recommended panel cut-outs for proper mounting
  • Compliance with related parts EN 3545-001 and EN 3545-002 for performance and arrangement specifications

• Marking and Delivery

  • Standardized marking includes identity block, date of manufacture, and manufacturer information
  • Connectors may be supplied with or without pre-installed female contacts depending on agreed delivery options

Applications

The EN 3545-003:2005 standard connectors with female contacts are primarily designed for aerospace electrical systems, including:

• Avionics and aircraft electrical wiring harnesses requiring robust and reliable rectangular connectors
• Fixed and removable electrical interfaces in aircraft, satellites, or space systems
• Environments with wide temperature variations, requiring sealed connectors for moisture protection
• Electrical systems requiring secure locking mechanisms and coding to avoid misconnection

These connectors provide reliable electrical performance and mechanical robustness necessary for high-reliability aerospace applications, ensuring safety and operational efficiency.

Related Standards

Organizations and professionals working with EN 3545-003:2005 should also be familiar with the following linked standards to ensure full compliance and interoperability:

• EN 3545-001: Technical specifications governing design and testing parameters for connectors in this family.
• EN 3545-002: Defines performance and contact arrangements for aerospace series connectors.
• EN 2591-100: General test methods applicable to aerospace electrical and optical connection elements.
• EN 3155-002: Lists and usage guidelines for electrical contacts used within these connectors.

These standards collectively establish the framework for qualifying, manufacturing, and utilizing aerospace-grade rectangular connectors with sealed and non-sealed housings and locking mechanisms under extreme operating conditions.
