Overview
EN 4531-005:2012 is a CEN product standard for aerospace optical circular connectors - specifically the plug version in the family of single‑ and multi‑pin connectors with a triple‑start threaded coupling and flush contacts. The standard defines the required characteristics of mounted plugs used in aerospace electrical/optical systems and establishes how plugs are designated and marked for traceability and interchangeability.
Key topics and technical requirements
- Scope and purpose: Specifies characteristics of mounted plugs in the circular optical connector family coupled by a triple‑start threaded ring (flush contact style).
- Dimensions and masses: Reference figures and tables provide connector dimensions and mass values; dimensions and tolerances are given in millimetres. General dimensions reference EN 3645-008.
- Material and surface treatment: Material selection and surface finishes are controlled by cross‑reference to EN 4531-002.
- Optical, mechanical and climatic characteristics: Performance requirements (optical interfaces, mechanical robustness and environmental resistance) are defined by EN 4531-002 and EN 4531-001 as normative references.
- Designation system: Standardized description blocks include the basic standard number, plug identification, shell size code, contact arrangement, sleeve code, environmental class and polarization - supporting unambiguous ordering and documentation.
- Marking and traceability: Marking must include the part identification per Clause 5, date of manufacture (year and week) and manufacturer name or trademark; EN 2424 code P may be used where required.
- Normative references: EN 4531-001 (technical specification), EN 4531-002 (performance and contact arrangements), EN 2424 (marking) and EN 3645-008 are referenced as indispensable for correct application.
Applications and users
- Who uses it: Aerospace OEMs, avionics designers, harness and connector manufacturers, maintenance/repair organisations, procurement teams, and qualification/test facilities.
- Typical applications: Aircraft and spacecraft avionics, flight‑critical sensors and data links, high‑reliability optical interconnects in aerospace and defence platforms where standardized optical circular plug interfaces and threaded coupling are required.
- Practical value: Ensures mechanical compatibility, environmental performance and traceability across suppliers and systems, simplifying procurement, qualification and maintenance of optical connectors in aerospace programs.
