Overview
EN 4531-003:2012 is a CEN product standard in the aerospace series that defines the characteristics of square flange receptacles within the family of optical, circular connectors coupled by a triple start threaded ring (flush contacts). Prepared under ASD-STAN and approved by CEN, this standard specifies the physical, marking and designation requirements for mounted square-flange receptacles used in aerospace applications. It supersedes EN 4531-003:2007 and is intended for use across national standards bodies in Europe.
Key topics and requirements
- Scope and application
- Covers mounted square flange receptacles for circular optical connectors with triple start threaded coupling and flush contacts.
- Dimensions and masses
- References EN 3645-003 for panel cut-outs and dimensional details. Mass values are provided in the standard (see Table 1) by shell size and class.
- Material and surface treatment
- Material types and surface finishes are specified by reference to EN 4531-002.
- Optical, mechanical and climatic characteristics
- Performance, contact arrangements and environmental classes are defined by EN 4531-002 and EN 4531-001 (technical specification).
- Designation and marking
- Provides a standardized designation format (including basic standard number, shell size, arrangement, sleeve and environmental class, polarization).
- Marking must include identification per Clause 5, manufacture date (year/week) and manufacturer name/trademark or conform to EN 2424 code P where required.
- Normative references
- The standard relies on EN 4531-001, EN 4531-002, EN 3645-003 and EN 2424 for essential specifications and test/performance requirements.
Applications and users
EN 4531-003:2012 is intended for:
- Aerospace and avionics system designers specifying optical connector interfaces.
- Connector and component manufacturers producing square flange receptacles for aerospace use.
- Procurement and quality assurance teams ensuring parts conformity and traceability.
- Maintenance, repair and overhaul (MRO) organizations and test laboratories validating connector fit, marking and environmental suitability. Typical applications include optical interconnects in aircraft, satellites, launch vehicles and other aerospace platforms where robust, polarized, flush-contact circular optical connectors are required.
