Overview
SIST EN 4645-003:2010 is a European standard developed by CEN that defines the specifications for aerospace optical connectors, specifically square flange receptacles within the family of circular connectors featuring triple start threaded coupling. These connectors incorporate a self-locking 1.25 mm diameter ferrule with a removable alignment sleeve holder, designed to meet the rigorous demands of aerospace applications.
This standard ensures uniformity, reliability, and high performance for mounted square flange receptacle connectors used in aerospace electrical equipment and systems. It complements other parts of the EN 4645 series and related aerospace standards, offering manufacturers and engineers clear guidelines on dimensions, materials, mechanical and optical characteristics, and quality management.
Key Topics
- Connector Type: Circular optical connectors with single or multipin configurations, secured by a triple start threaded ring for self-locking.
- Mounting Style: Square flange receptacle designed for panel mounting, providing robust mechanical stability.
- Ferrule Diameter: 1.25 mm optical ferrule with removable alignment sleeve holders enabling precise fiber alignment.
- Dimensions and Mass: Detailed sizing and maximum mass specified for various shell sizes (11 to 25 mm), ensuring compatibility across aerospace systems.
- Material and Surface Treatment: Specified in related standards (EN 4645-002), targeting durability and environmental resistance.
- Panel Cut-Out: Conforms to EN 3645-003, standardizing mounting interface dimensions.
- Optical, Mechanical, and Climatic Characteristics: Performance requirements aligned with EN 4645-001 (connectors) and EN 4639-101/102 (optical contacts), ensuring operation under aerospace environmental conditions.
- Marking and Identification: Includes manufacturer identification, production date, and codes following EN 2424:2008 for traceability.
- Quality Assurance: Compliance with EN 9133 quality management system for aerospace standard parts guarantees reliability and manufacturing excellence.
Applications
EN 4645-003 connectors are critical components in aerospace communication and control systems requiring high-precision optical data transmission. Typical applications include:
- Aircraft avionics and instrumentation that demand robust, vibration-resistant optical connections.
- Spacecraft optical data links, where self-locking connectors ensure secure coupling in harsh conditions.
- Military aerospace platforms requiring standardized, reliable optical interconnections for mission-critical systems.
- High-performance aerospace sensor networks, leveraging optical fibers for electromagnetic immunity and lightweight cabling.
- Satellite communication systems using standardized, removable alignment sleeve holders to simplify maintenance and upgrades.
The standard’s focus on consistent mechanical and optical parameters facilitates interoperability between suppliers and end users, reducing system integration risks and enhancing operational safety.
