Overview

EN 2997-016:2010 is a European standard within the aerospace series that specifies requirements for electrical circular connectors, specifically plugs with integrated accessories. These connectors are coupled by a threaded ring and are designed to be either fire-resistant or non-fire-resistant. The standard covers operating temperature ranges from -65 °C up to 175 °C continuous, 200 °C continuous, and peak temperatures up to 260 °C.

This product standard is part 016 in the EN 2997 series and addresses plugs with integrated accessories used in aerospace electrical systems. Its detailed specifications support reliability, safety, and interchangeability in demanding aerospace environments.

Key Topics

  • Connector Family: Circular electrical connectors coupled by threaded ring
  • Plug Type: Plugs with integrated accessory components such as housings and seals
  • Fire Resistance: Available in both fire-resistant and non-fire-resistant variants
  • Operating Temperatures: Ranges include -65 °C to 175 °C continuous, 200 °C continuous, and peak usage up to 260 °C
  • Materials: Housings made from various materials including stainless steel and aluminum alloys, with specific surface treatments for corrosion resistance (e.g., cadmium-plated, nickel-plated, passivated stainless steel)
  • Classes and Models: Multiple classes defined by material, corrosion resistance, temperature rating, and the presence of grounding spring systems (e.g., W, WS, K, R, RS, S, KE, KV, SV, SE)
  • Dimensions and Mass: Detailed sizing for housings with weights listed for stainless steel and aluminum designs
  • Marking: Identification codes, manufacturing date, and manufacturer information requirements to ensure traceability
  • Compatibility: Defined possible combinations with corresponding receptacles and protective covers per related EN 2997 series standards

Applications

EN 2997-016 connectors play a critical role in aerospace electrical systems where safety, durability, and functionality under extreme conditions are mandatory. Key applications include:

  • Aircraft Electrical Wiring: Ensuring secure, fire-resisting connections for onboard electrical systems and avionics
  • Spacecraft Systems: Withstanding extreme temperatures and vibrations during launch and operation
  • Defense and Military Aerospace Equipment: Providing robust connectors suitable for harsh operational environments
  • High-Temperature Environments: Electrical systems requiring connectors that maintain integrity at elevated temperatures up to 260 °C peak
  • Corrosive Environments: Aerospace and related sectors requiring connectors with high resistance to salt mist and other corrosive agents

These connectors enable reliable electrical connections vital for mission-critical aerospace components.
