Overview
EN 2997-005:2016 is a European Standard developed by CEN specifically for aerospace electrical connectors. It defines the product standard for hermetic square flange mounted receptacles in circular electrical connectors that are coupled by a threaded ring. These connectors are designed to be either fire-resistant or non fire-resistant and are engineered to operate reliably within a broad temperature range from -65 °C to 175 °C continuous, with some models capable of handling up to 200 °C continuous and 260 °C peak temperatures. This standard ensures consistent quality, safety, and interoperability across aerospace electrical systems.
This document caters to a critical niche in aerospace applications requiring hermetic sealing to protect sensitive avionics and electrical systems from environmental hazards such as moisture, dust, and corrosive elements.
Key Topics
Scope and Applicability: Focuses on hermetic square flange receptacles within the broader family of circular electrical connectors coupled by threaded rings. Applies exclusively to the connector class defined within the document, while corresponding plugs and protective covers are standardized under EN 2997-008 and EN 2997-009, respectively.
Dimensional Requirements: Precise mechanical dimensions and tolerances for housing sizes (08 to 28) are specified to ensure compatibility and ease of integration. Mounting hole placements and panel cut-out dimensions are also rigorously defined for reliable installation.
Materials and Surface Treatment: Shell housings are typically made of passivated stainless steel with a salt mist resistance of 500 hours, contributing to corrosion resistance and durability in harsh aerospace environments.
Thermal Performance: Classified for operation under wide temperature extremes, supporting applications exposed to both extreme cold and heat, including fire events.
Marking and Identification: Clear marking guidelines include unique identity blocks, manufacturing dates, and manufacturer trademarks to enable traceability and quality assurance.
Product Classification: Connectors are classified by housing material and temperature rating, for example:
- Class Y: Hermetic receptacle with stainless steel housing, 200 °C continuous max operation.
- Class YE: Hermetic receptacle with stainless steel housing, capable of 260 °C peak temperatures.
Applications
EN 2997-005:2016 connectors are primarily suited for aerospace and defense electrical systems where hermetic sealing and reliable high-temperature operation are mandatory. Typical applications include:
- Aircraft avionics and sensor systems requiring protection from moisture and contaminants.
- Electrical wiring in engine compartments and other areas exposed to harsh thermal cycles.
- Systems demanding high reliability under fire conditions or temperature spikes.
- Spacecraft and satellite equipment where long-term durability and environmental resistance are critical.
The standardized interface and mounting provisions facilitate integration into aircraft panels and structural components while maintaining hermetic integrity.
Related Standards
For a complete connector system compliant with aerospace requirements, EN 2997-005:2016 should be used alongside the following complementary standards from the EN 2997 series:
- EN 2997-001: Overall technical specifications covering circular electrical connectors by threaded ring.
- EN 2997-002: Performance specifications and contact arrangements for these connectors.
- EN 2997-008: Product standard specifying plugs compatible with the receptacles.
- EN 2997-009: Protective covers designed for receptacles to maintain environmental protection when disconnected.
These standards together establish a comprehensive framework ensuring interoperability, safety, and performance consistency across aerospace electrical connector products.
