Overview
SIST EN 3646-008:2009 is a European standard developed by CEN that specifies the product requirements for plug connectors within the aerospace series of electrical circular connectors. These connectors feature a bayonet coupling mechanism designed to operate continuously at high temperatures of 175 °C or 200 °C. The standard covers the characteristics, designation, marking, and technical specifications relevant to plugs intended for extreme temperature environments ranging from -65 °C up to 200 °C.
This standard applies to various plug models defined in Table 2 of the document and is part 008 in a series that addresses different components such as contacts, receptacles, and protective covers. By adhering to EN 3646-008, manufacturers and aerospace engineers ensure compatibility, safety, and reliability in electrical connector systems exposed to harsh aerospace operational conditions.
Key Topics
- Temperature Range: Defines continuous operating temperature suitability between -65 °C and 175 °C or 200 °C for long-term reliability in aerospace environments.
- Connector Type: Circular electrical connectors with bayonet coupling to ensure secure, vibration-resistant connections.
- Materials and Surface Treatment: Specifies aluminum alloy (black anodized or nickel-plated) and olive green cadmium alloy finishes that offer corrosion resistance and durability.
- Design Specifications: Dimensions, mass, and tolerances are standardized to ensure interchangeability and compatibility with mating receptacles as outlined in related parts of the EN 3646 series.
- Plug Models: The document details multiple models differing in sealing, housing material, contact type, and thermal rating to meet diverse aerospace application requirements.
- Marking Requirements: Includes manufacturer part number, date of manufacture, and trade marks for traceability and quality assurance.
- Associated Components: Cross-references standards EN 3646-002 for contacts and accessories, and EN 3646-003 to EN 3646-007 for receptacles, providing a complete framework for electrical connector systems.
Applications
EN 3646-008 plugs are fundamental components in aerospace electrical systems requiring:
- High-temperature reliability: Suitable for environments such as aircraft engines, avionics, and other aerospace subsystems exposed to elevated temperatures.
- Secure and durable electrical connections: Bayonet coupling ensures fast and secure connection cycles while resisting mechanical stress and vibrations inherent to aerospace operations.
- Interfacing with standardized connector families: Compatibility with a wide range of receptacles and covers in the EN 3646 series, allowing modular assembly and maintenance.
- Harsh environmental conditions: Materials and finishes specified enable resistance to corrosion, salt mist, and electromagnetic interference, critical in aerospace and defense applications.
These connectors are widely employed in commercial and military aircraft, spacecraft, and high-performance aerospace equipment where reliability, safety, and standard compliance are paramount.
