Overview
SIST EN 4644-142:2017 is a European standard developed by CEN that defines the specifications for size 4 receptacles used in aerospace electrical and optical connectors. This standard focuses on modular, rectangular connectors with rectangular inserts designed for rack and panel applications. The connectors covered operate continuously at high temperatures of 175 °C or 125 °C, ensuring reliability in demanding aerospace environments. SIST EN 4644-142:2017 complements EN 4644-141, which specifies the corresponding size 4 plug.
This product standard ensures uniformity and interoperability in aerospace electrical and optical connector components, supporting secure connections vital for the aerospace and defense industries.
Key Topics
- Scope and Applicability: Specifies size 4 receptacle connectors for rack and panel applications within the modular aerospace connector series.
- Design and Dimensions: Detailed dimensions, including panel cut-out recommendations and self-locking thread housing types (M3 × 0.5 and 4-40 UNC 2B), ensure precision mounting and compatibility.
- Operating Temperature: Rated for continuous operation at elevated temperatures of 175 °C or 125 °C, suitable for harsh aerospace conditions.
- Coding System: Provides an advanced panel cut-out coding system for correct connector and panel matching, preventing misconnection through configurable coding pins and holes.
- Mass and Marking:
- Maximum mass of the connector receptacle is 80 grams.
- Markings include manufacturer identification, date of manufacture, and housing identification for traceability and maintenance.
- Technical References: Cross-referenced normative documents such as EN 4644-001 (technical specifications) and EN 4644-002 (performance and contact arrangements) ensure comprehensive compliance.
Applications
SIST EN 4644-142:2017 connectors are primarily designed for aerospace and defense electrical and optical systems requiring modular, high-reliability rectangular connectors. Key application areas include:
- Aircraft Avionics Systems: Reliable electrical and optical signal connections in cockpit controls and instrumentation.
- Spacecraft and Satellites: High-temperature tolerance critical for space environments.
- Military Aerospace Equipment: Ruggedized panel and rack mount receptacles for communication, power, and sensor systems.
- Rack-Based Equipment: Standardized interface connectors in rack enclosures for easy integration and maintenance.
The standard’s focus on self-locking threads and coding ensures secure mechanical retention and error-proof connection, essential for safety-critical aerospace operations.
Related Standards
- EN 4644-001: Technical specification for modular rectangular aerospace connectors, providing detailed mechanical and environmental requirements.
- EN 4644-002: Defines performance criteria and contact arrangements for these connectors to ensure electrical integrity and durability.
- EN 4644-141: Specifies the size 4 plug counterpart to the receptacle covered by EN 4644-142, ensuring compatibility within the connector family.
These interconnected standards provide a comprehensive framework for electrical and optical aerospace connectors, offering manufacturers and users guidance on design, testing, and quality requirements.
For professionals in aerospace engineering, defense manufacturing, and system integration, understanding and applying SIST EN 4644-142:2017 ensures high-quality connector solutions capable of performing under extreme temperatures and operational stresses while maintaining precise rack and panel compatibility. This standard supports seamless interoperability, enhances safety, and simplifies inventory management of aerospace electrical and optical connectors.
