Overview
EN 4531-004:2012 is a CEN product standard in the Aerospace series that specifies the characteristics of mounted jam nut receptacles for circular optical connectors with a triple-start threaded coupling and flush contacts. It defines the dimensional, marking and designation requirements for jam nut mounted receptacles used in single- and multipin optical connector families intended for aerospace applications. This edition supersedes EN 4531-004:2007 and was approved by CEN in 2011.
Key topics and requirements
- Scope: Characteristics of mounted jam nut receptacles within the triple-start threaded circular optical connector family.
- Dimensions and masses: Dimensional details reference EN 3645-009; a shell-size-to-mass table (Table 1) is provided for design and weight budgeting.
- Materials and surface treatment: Material and finish requirements are covered by cross-reference to EN 4531-002.
- Panel cut-out and mounting: Panel cut-out shapes and jam nut mounting details are specified via EN 3645-009.
- Optical, mechanical and climatic performance: Optical interface, mechanical durability and environmental characteristics are governed by EN 4531-001 and EN 4531-002 as applicable.
- Designation and marking: Prescribes connector identification format (example designation block shown), mandatory marking elements including standard identification, date of manufacture (year, week) and manufacturer’s name/trademark or EN 2424 code P.
- Normative references: EN 4531-001, EN 4531-002, EN 3645-009, EN 2424 are indispensable for application of this standard.
Applications and users
EN 4531-004 is intended for use where reliable, standardized panel-mounted optical receptacles are required in aerospace equipment. Typical applications:
- Aircraft and spacecraft avionics and communication systems
- Panel-mounted optical interfaces for sensors, datalinks or in-flight entertainment
- Retrofit and maintenance operations where replacement receptacles must meet established form-fit-function standards
Primary users:
- Connector manufacturers and component designers (mechanical and optical)
- Aerospace OEMs and subcontractors specifying connector procurement
- Quality, test and certification engineers verifying conformity
- Maintenance, repair and overhaul (MRO) teams replacing panel receptacles
Related standards
- EN 4531-001 - Technical specification (optical performance, terms)
- EN 4531-002 - Performance and contact arrangements; materials/surface treatment
- EN 3645-009 - Dimensions and panel cut-outs for jam nut mounting
- EN 2424 - Marking of aerospace products
EN 4531-004 helps ensure interoperability, weight predictability and consistent marking for jam nut optical receptacles in aerospace systems-essential for procurement, design validation and regulatory compliance.
