Overview
EN 4531-002:2016 - published by CEN and part of the Aerospace series - specifies the performance and contact arrangements for circular optical connectors with flush contacts, coupled by a triple‑start threaded ring. It applies to single‑ and multi‑pin optical circular connectors used in aerospace and related applications. EN 4531-002:2016 supersedes the 2012 edition and is published alongside other EN 4531 parts and related product standards.
Key topics and technical requirements
- Scope: Defines performance criteria and contact layouts for circular optical connectors coupled by a triple‑start threaded ring.
- Environmental classes and corrosion resistance: Identifies material/plating classes (composite, aluminium, stainless steel, etc.) and associated salt spray requirements (examples: cadmium plated composite – 2000 h; zinc‑nickel aluminium – 500 h; nickel plated aluminium – 48 h).
- Shell sizes and contact arrangements: Standard shell sizes (9, 11, 13, 15, 19, 21, 25) map to number of optical ways (1, 2, 4, 6, 8, 12, 24) and defined arrangement codes.
- Sleeve coding: Sleeve codes (A, B, C) describe insert sleeve variants (A = no sleeve; B = cavity for flushed contact; C = cavity for recessed contact). Sleeve materials and female insert variants are referenced to EN 4531-001.
- Type codes: Connector type coding examples include square flange receptacle (003), jam nut receptacle (004), and plug (005).
- Compatibility rules: Provides compatibility/combinations for plug and receptacle shells and guidance on which pairings achieve declared performance or require design authority approval.
- Referenced operational aspects: Optical performance is defined relative to cable/product standards; climatic, mechanical, assembly, cleaning, tooling and rear/accessories references point to associated product parts.
Applications and users
EN 4531-002 is intended for:
- Aerospace and defense connector designers and manufacturers specifying aerospace optical connectors and assemblies.
- Systems engineers and integrators in aircraft, spacecraft and military platforms selecting connector types, shell sizes and materials.
- Procurement, quality assurance, maintenance and regulatory teams verifying connector performance, corrosion resistance and interchangeability.
- Suppliers of connector contacts, filler plugs and rear accessories who must follow the referenced EN 4531 product parts.
Practical uses include selecting appropriate shell size and material class for environmental resistance, ensuring correct contact arrangements for optical channels, and verifying compatibility of plug/receptacle pairings.
Related standards
- EN 4531 (all parts) - product standards for optical connectors and contacts (EN 4531‑001, EN 4531‑101 to EN 4531‑799, EN 4531‑901)
- EN 3645‑001 / EN 3645‑002 - related electrical connector specifications and rear/accessories
- Other EN 4531 product-specific parts for assembly, termination, cleaning and tooling
