Overview
The EN 4531-901:2012 is a European Standard developed by CEN and ASD-STAN that specifies the product requirements for filler plugs used in aerospace optical circular connectors. These connectors feature a triple start threaded ring coupling and flush contacts, supporting both single and multi-pin configurations. This standard focuses exclusively on male and female filler plugs designed to fit within this series of advanced aerospace optical connectors, ensuring reliable sealing and mechanical integrity.
By standardizing the design, dimensions, material characteristics, and operating conditions of filler plugs, EN 4531-901:2012 facilitates consistent quality, interchangeability, and long-term performance in aerospace optical interconnection systems.
Key Topics
- Scope: Defines characteristics for filler plugs (male and female) within circular optical connectors featuring a triple start threaded coupling.
- Configuration and Dimensions: Detailed illustrations and measurements are provided for filler plugs, with precise tolerances to ensure interoperability and secure fitting.
- Material Specifications: Male and female filler plugs use specified elastomeric materials to withstand harsh aerospace environmental conditions.
- Operating Temperature:
- Long-term use: from -65 °C to 125 °C (for 1,000 hours)
- Short-term use: from -65 °C to 150 °C (for 100 hours)
- Designation and Identification: Clear coding system for filler plugs aligns with the EN 4531 series for easy product identification.
- Technical Reference: Cross-references EN 4531-001 for broader connector technical specifications applicable to the series.
Applications
- Aerospace Optical Systems: The standard is crucial for optical data transmission connectors used in aircraft, spacecraft, and related aerospace vehicles.
- Defence Industry: Ensures compatibility and reliability in military aerospace optical interconnects where environmental resilience and precision are critical.
- Electronic Equipment: Supports ruggedized electronic systems requiring sealed optical connectors to maintain signal integrity in demanding conditions.
- Maintenance and Spare Parts: Standardized filler plugs allow for efficient replacement and maintenance, protecting connectors from contamination and damage when not in use.
Related Standards
- EN 4531-001: The technical specification standard for optical circular connectors in aerospace, providing in-depth electrical, mechanical, and material requirements.
- Other aerospace connector standards addressing optical and electrical connection systems may complement the EN 4531 series, ensuring comprehensive coverage of aerospace interconnect needs.
By adhering to EN 4531-901:2012, aerospace manufacturers and maintenance organizations can ensure that filler plugs meet rigorous performance standards for optical circular connectors, enhancing system reliability and safeguarding sensitive communication links in extreme aerospace environments. This product standard plays a vital role in maintaining the integrity and functionality of critical optical connections throughout the aerospace industry.
