Overview

EN 4645-004:2009 is a CEN product standard in the Aerospace series that specifies the characteristics of mounted jam nut receptacles for a family of circular optical connectors. These connectors use a triple-start threaded coupling, are self‑locking, and accept 1.25 mm diameter ferrules with a removable alignment sleeve holder. The standard defines how jam nut receptacles are dimensioned, identified and integrated into aerospace panels.

Key topics and technical requirements

  • Scope: Mounted jam nut receptacles for circular optical connectors coupled by a threaded ring (triple‑start threading).
  • Dimensions and masses: Detailed dimensional drawings and mass limits are specified (see Figure 1 and Table 1 in the standard). Connector sizes cover shell classes (e.g., sizes 11–25) with defined maximum masses.
  • Material and surface treatment: Material selection and finishes are referenced to EN 4645-002:2009 (see its Table 1 for options).
  • Panel cut‑out and mounting: Panel cut‑out geometry and mounting details are to conform to EN 3645-003.
  • Optical, mechanical and climatic performance: Performance characteristics (optical contact behaviour, mechanical robustness, environmental/climatic requirements) are covered by EN 4645-002 and the specific optical contact product standards (EN 4639-101 / EN 4639-102).
  • Marking and designation: Receptacles must be marked with identification, date of manufacture (year and week) and manufacturer name/trademark, or comply with EN 2424:2008 code P when required.
  • Quality and qualification: Quality and qualification procedures follow EN 9133 for aerospace standard parts.
  • References: Normative references included within EN 4645-004 link to related technical and product standards necessary for full implementation.

Applications and who uses this standard

  • Engineers and designers specifying aerospace optical interconnects for avionics, flight controls, sensors, and airborne data systems.
  • Manufacturers of circular optical connectors and panel‑mounted receptacles who require consistent mechanical, optical and mounting specifications.
  • Procurement and compliance teams verifying part conformity with European aerospace standards.
  • Test and quality managers applying qualification, marking and traceability per aerospace quality requirements.
