Overview
EN 3733-103:2008 is a CEN product standard in the Aerospace series that specifies the characteristics of protective covers for single-channel fibre-optic jam nut receptacle connectors rated for continuous operation up to 150 °C. The standard defines required materials, mass limits, and the interface relationships to companion product and technical specifications. It is intended to ensure reliable protective performance and interchangeability in aerospace electrical and optical systems.
Key Topics
- Scope and Purpose: Defines protective covers for jam nut receptacles used with single-channel optical circular connectors coupled by a self-locking ring, operating up to 150 °C continuous.
- Materials: Specifies construction materials: nickel-copper alloy cover, nylon cord and fluorosilicone seal, selected for temperature resistance and environmental protection.
- Dimensions and Mass: Interface dimensions are shown in the standard's figure and include dimensional limits such as Ø 20.63 mm max and Ø 14.98 mm min; mass is limited to 18.1 g max (see figure for full details).
- Designation and Marking: Provides a designation example (e.g., COVER, RECEPTACLE, JAM NUT EN3733-103B). Marking requirements are referenced to EN 3733-001.
- Technical and Qualification Links: Connector interface dimensions, test tables and qualification approval requirements are contained in EN 3733-001. The list of product types and codification is in EN 3733-002. Test methods reference EN 2591-100 where applicable.
Applications
This product standard supports practical aerospace applications by ensuring protective covers are:
- Compatible with receptacles defined in EN 3733-006 and listed combinations in EN 3733-002.
- Suitable for use in high-temperature environments up to 150 °C, protecting optical termini from contamination and mechanical damage during storage, maintenance and service.
- Appropriate for avionics, aircraft wiring harnesses, ground-support equipment and other aerospace installations where single-channel optical connectors are used.
Benefits include improved interchangeability, consistent protective performance, and a clear route to qualification when used with the referenced technical specification and test methods.
