Overview

SIST EN 2997-006:2024 is a European standard developed by CEN that specifies the product requirements for hermetic jam-nut mounted receptacles in the aerospace series of circular electrical connectors. These connectors are coupled by a threaded ring and are designed for use in critical aerospace environments. The standard supports connectors that operate under strict fire-resistant or non fire-resistant conditions and function reliably across extreme operating temperatures ranging from -65 °C to 175 °C continuous, up to 200 °C continuous, with peak tolerance up to 260 °C.

This document is vital for manufacturers, designers, and engineers working with aerospace electrical systems, ensuring uniformity, safety, and performance in harsh environmental conditions. It complements related parts of the EN 2997 series such as plugs (EN 2997-008), protective covers (EN 2997-009), jam-nuts (EN 2997-012), and O-ring seals (EN 2997-013).

Key Topics

  • Product Scope
    Focuses on hermetic jam-nut mounted receptacles within the family of circular connectors coupled by threaded rings, essential for reliable aerospace electrical connections.

  • Design and Dimensions
    Specifies exact dimensions, mass, and tolerances for housing sizes 08 to 28, ensuring interchangeability and compatibility. Includes detailed panel cut-out dimensions for mounting.

  • Material and Surface Treatment
    Defines requirements for materials such as passivated stainless steel housings resistant to corrosion (500 hours salt mist resistance) with solder contacts, tailored to withstand high temperatures and harsh aerospace environments.

  • Mechanical Requirements
    Details the tightening torque values for attachment nuts by housing size, assuring secure and reliable mechanical fastening.

  • Hermetic Seal Characteristics
    Ensures environmental protection through hermetic sealing, suitable for aerospace applications demanding contamination-free and airtight electrical connections.

  • Classification and Marking
    Connectors are classified by characteristics such as temperature rating and material. Marking requirements include manufacturer identification, date of manufacture, and identity blocks.

Applications

EN 2997-006 connectors are specifically designed for demanding aerospace and defense electrical systems, including but not limited to:

  • Avionics and aircraft electrical wiring harnesses
  • Aerospace onboard power and signal distribution systems
  • Fire-resistant electrical connections critical to aircraft safety
  • Situations requiring hermetic sealing to prevent ingress of moisture, dust, or gases
  • Environments with exposure to extreme temperature fluctuations and corrosive conditions

These connectors ensure reliable electrical performance and mechanical integrity, vital for mission-critical applications where failure is not an option.

Related Standards

The EN 2997-006 standard works in conjunction with other parts of the EN 2997 aerospace connector series to form a comprehensive product and performance specification:

  • EN 2997-001: Technical specification for the overall series of aerospace circular connectors
  • EN 2997-002: Specification of performance and contact arrangements for connectors
  • EN 2997-008: Product standard for circular electrical plugs compatible with these receptacles
  • EN 2997-009: Protective covers for connectors to maintain operational integrity
  • EN 2997-012: Jam-nuts used for securing the receptacles
  • EN 2997-013: O-ring seals ensuring environmental sealing for jam-nut mounted connections
  • ISO 263: Provides standards for screw threads relevant to connectors’ mechanical components

Together, these standards provide comprehensive guidance for the design, manufacture, and use of aerospace-grade circular electrical connectors.
