Overview
EN 4644-025:2015 is a CEN (ASD-STAN) product standard for an aerospace-series size 2 receptacle with flange used in modular rectangular electrical and optical connectors. It covers the receptacle intended for disconnect applications, compatible with plugs defined in EN 4644-021, EN 4644-022 or EN 4644-023. The family is specified for continuous operating temperatures of 175 °C (or 125 °C) and is part of a broader series for high-reliability aerospace plug-and-socket devices.
Key topics and requirements
- Product scope: Size 2 receptacle, flange-mounted, classes A, C and E.
- Operating temperature: Continuous rating at 175 °C (or 125 °C) as per the EN 4644 series.
- Mechanical characteristics:
- Mounting options shown in standard figures: flange with two clear holes or threaded mounting holes.
- Hole options: two Ø 3.09 min (3.20 max) clear holes, or two 6-32 UNC self-locking threaded holes, or two 4-40 UNC self-locking threaded holes.
- Panel cut-out and flange dimensions are specified in the figures referenced by the standard (see Figures 1–3).
- Mass limit: 60 g max.
- Screw head maximum diameter referenced in the illustrations.
- Designation and identification:
- Example format: ELECTRICAL CONNECTOR, SIZE 2 RECEPTACLE - EN 4644-025ADX, where the code identifies shell class, housing type (D, F, L) and polarization.
- Polarization, shell class and axis references (Ar, Br, Cr) follow EN 4644-001 / EN 4644-002 conventions.
- Normative references: The standard is used in conjunction with EN 4644-001 (technical spec), EN 4644-002 (performance/contact arrangements) and the associated plug product standards (EN 4644-021/022/023).
Applications and who uses it
- Typical use in aerospace electrical and optical systems where modular rectangular connectors are required for disconnectable interfaces.
- Relevant for:
- Aerospace design and systems engineers specifying connector interfaces
- Connector manufacturers and component suppliers
- Installation and maintenance technicians for airframe and avionics harnesses
- Procurement and certification teams ensuring compliance with European aerospace connector standards
- Practical application examples: panel-mounted receptacles on avionics racks, harness termination points, and disconnect interfaces in high-temperature zones (engine bay, auxiliary systems), where standardized mechanical and mounting dimensions are critical.
