EN 3372-011:2007

Overview

EN 3372-011:2007 is a European standard that defines the product requirements for dummy receptacles within the aerospace series of circular electrical connectors. These connectors feature medium to high contact density and are designed with scoop-proof bayonet coupling. The standard covers the performance and dimensional characteristics of dummy receptacles intended for operating temperatures ranging from -65 °C up to 175 °C or 200 °C continuous use.

Developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and approved by CEN, this standard ensures uniformity and interoperability of electrical connectors used in aerospace applications across member countries. It is referenced alongside related standards such as EN 3372-001 for technical specifications and EN 3372-008 for plug types.

Key Topics

• Scope and Application
  Specifies dummy receptacles in the family of circular connectors with bayonet ring coupling, suitable for aerospace systems requiring reliable electrical performance under demanding temperature ranges.

• Dimensional and Mechanical Characteristics
  Detailed dimensions, mass, panel cut-out sizes, and mounting configurations are standardized to ensure interchangeability and compatibility (see Figures 1 & 2, Tables 1 & 2).

• Material and Surface Treatments
  Defines connector classes with materials like cadmium-plated and nickel-plated aluminum alloys, optimized for corrosion resistance and thermal endurance:

  • Class W: Cadmium-plated, olive drab finish, salt mist resistance for 500 hours, max continuous temperature 175 °C.
  • Class F: Nickel-plated aluminum, salt mist resistance for 48 hours, max continuous temperature 200 °C.

• Marking and Designation
  Includes requirements for clear and traceable markings with manufacturer info, date of manufacture, and product codes to facilitate identification and quality control.

• Compliance and Compatibility
  Establishes possible plug and receptacle combinations according to connected standards, supporting robust aerospace electrical system design.

Applications

EN 3372-011:2007 supports the aerospace industry by standardizing dummy receptacles critical for:

• Electrical system prototyping and testing where connectors simulate real interfaces.
• Ensuring consistent physical and electrical interface parameters for dummy connectors used in aerospace wiring harnesses.
• Environments requiring high reliability under thermal extremes from -65 °C to 200 °C continuous operation.
• Military and civil aerospace platforms adopting common connector families to reduce maintenance complexity and enhance interchangeability.

This standard is particularly vital for aerospace electrical engineers, connector manufacturers, and quality assurance specialists focused on connector systems that must withstand extreme conditions while ensuring safety and performance.
