Overview
EN 4644-026:2015 is a CEN product standard in the Aerospace series for rectangular, modular electrical and optical connectors. It specifies the size 2 receptacle with ground block, classes B and F, intended for disconnect applications and for continuous operating temperatures of 175 °C (or 125 °C). The standard defines mechanical interfaces, panel cut‑outs, mass limits and designation rules for this modular receptacle family used in aerospace equipment.
Key topics and requirements
- Scope and application: Size 2 receptacle for disconnect use within the EN 4644 modular rectangular connector family. The mating plugs are specified in EN 4644-021, EN 4644-022 or EN 4644-023.
- Operating temperature: Rated for continuous operation at 175 °C (alternate 125 °C option is noted).
- Mechanical dimensions and panel cut‑out: Detailed layouts and recommended panel cut‑outs are provided (figures in the standard). Key features include four self‑locking 6‑32 UNC threads and defined axis references per EN 4644‑001.
- Mass: Maximum mass for the receptacle is specified as 80 g.
- Housing and mounting types: Housing variations (e.g., with or without mounting holes) and shell class designators are defined. Example designation format: ELECTRICAL CONNECTOR, SIZE 2 RECEPTACLE EN 4644-026BAX (where B/A indicate housing type and X polarization code).
- Designation and identification: Rules for product identity blocks (shell class, housing type, polarization code) support procurement and interchangeability.
- Normative dependencies: Terms, definitions and performance parameters reference EN 4644-001 and EN 4644-002.
Applications and users
- Typical applications: aircraft and aerospace systems requiring compact modular electrical/optical interconnections, especially where high continuous temperatures and grounding are required (power, avionics, environmental control systems).
- Primary users:
- Aerospace connector manufacturers and component designers
- System integrators and OEMs specifying connector interfaces
- Qualification and test laboratories verifying mechanical and environmental compliance
- Procurement and maintenance teams ensuring parts interchangeability and correct panel cut‑outs
