Overview
EN 4644-024:2015 is a CEN product standard in the EN 4644 aerospace connector series. It specifies the size 2 receptacle used for disconnect applications in modular rectangular electrical and optical connectors with rectangular inserts. The standard applies to connectors rated for continuous operating temperatures of 175 °C (or 125 °C) and covers mechanical dimensions, panel cut-out recommendations and product designation for classes A, C and E.
The matching plug is defined in EN 4644-021, EN 4644-022 or EN 4644-023. Normative references that are indispensable for application include EN 4644-001 (technical specification) and EN 4644-002 (performance and contact arrangements).
Key Topics
- Scope and use: Defines the receptacle size 2 for disconnect applications within the modular rectangular connector family.
- Operating temperature: Continuous rating of 175 °C (or 125 °C), consistent with the EN 4644 series.
- Mechanical requirements: Dimensions and recommended panel cut-out provided (see Figures 1–3 in the standard). Key panel options include:
- Two ∅ 3,09 mm min. (3,20 mm max.) clear holes
- Two 6-32 UNC self-locking threaded holes
- Two 4-40 UNC self-locking threaded holes
- Mass limit: Receptacle mass specified as 50 g max.
- Housing and mounting types: Housing variants are identified (B, D, F, L) with the following general characteristics:
- B: with no mounting holes
- D: with 2 × ∅ 3,09 min. (3,20 max.) clear holes
- F: with 2 × 6-32 UNC threaded holes
- L: with 2 × 4-40 UNC threaded holes
- Designation and identification: Example designation and identity block format are provided; shell class and polarization codes reference EN 4644-002.
Applications
EN 4644-024:2015 is intended for engineers, designers and procurement professionals specifying aerospace-grade connectors where:
- Reliable disconnect/receptacle interfaces are required for electrical and optical signal paths.
- High continuous operating temperatures (up to 175 °C) are part of the environmental profile.
- Repeatable panel mounting and dimensional interchangeability are necessary for system integration and maintenance.
Typical use cases include avionics equipment, harness terminations and modular connector assemblies where adherence to common product standards ensures compatibility across suppliers and platforms.
