Overview
SIST EN 3646-007:2015 is a European standard that specifies the requirements for hermetic electrical receptacles used in aerospace applications. These connectors feature a bayonet coupling circular design with a round flange mounted by welding or brazing. They are engineered to operate reliably within a continuous temperature range of −65 °C to 175 °C or 200 °C, making them suitable for high-temperature aerospace environments.
This standard is part of the larger EN 3646 series which covers various connector components, including plugs and protective covers, ensuring interoperability and quality in aerospace electrical systems. SIST EN 3646-007:2015 specifically covers models listed in Table 3 of the document and supersedes the earlier 2006 edition.
Key Topics
- Hermetic receptacles with welding/brazing mounting: Defines connectors with a round flange attachment method designed for high-integrity sealing and mechanical stability.
- Bayonet coupling mechanism: Provides quick and secure locking for circular electrical connectors used in aerospace applications.
- Operating temperature range: Continuous performance between −65 °C and up to 200 °C, suitable for extreme aerospace conditions.
- Material specifications: Housing typically made from passivated stainless steel with solder contacts to withstand harsh environments and maintain hermetic sealing.
- Dimensional standards: Detailed dimensions and tolerances, including housing sizes (from 08 to 24 series), panel cut-outs, and mass specifications.
- Marking and traceability: Includes mandatory manufacturer part numbers, manufacturing date codes, and trademark identification on both product and packaging.
- Compatibility: Coordinated with related standards covering plugs (EN 3646-008) and protective covers (EN 3646-009).
Applications
SIST EN 3646-007:2015 connectors are critical components in aerospace electrical systems, often used in:
- Aircraft wiring harnesses requiring secure, hermetically sealed electrical connections.
- Avionics systems subjected to extreme temperature fluctuations and demanding operational reliability.
- Spacecraft and satellite equipment where resistance to temperature extremes and vacuum conditions is essential.
- Defence aerospace platforms needing rugged, high-performance electrical connectivity with minimum risk of contamination.
- Environmental chambers and test rigs simulating aerospace conditions for component validation.
The robust design and strict manufacturing standards help ensure long-term reliability and safety in electrically critical aerospace installations.
Related Standards
To ensure full system compliance and compatibility, SIST EN 3646-007:2015 should be used in conjunction with:
- EN 3646-001: Technical specification for general bayonet coupling circular connectors operating at 175 °C or 200 °C.
- EN 3646-002: Defines performance specifications and contact arrangements for connectors in this aerospace series.
- EN 3646-008: Product standard for the corresponding bayonet coupling plugs compatible with EN 3646-007 receptacles.
- EN 3646-009: Specifies protective covers designed to safeguard hermetic connectors in operational environments.
These complementary standards ensure the full connector assembly meets aerospace operational, environmental, and interchangeability requirements.
SIST EN 3646-007:2015 is indispensable for manufacturers, suppliers, and aerospace engineers designing or selecting electrical connectors for high-temperature applications. Its adherence guarantees high-quality, hermetically sealed receptacles that meet the rigorous demands of the aerospace sector, supporting system reliability and safety.
