Overview

EN 4644-023:2015 is a European product standard in the aerospace series that defines the size 2 plug for disconnect applications in the family of modular rectangular electrical and optical connectors with rectangular inserts. The standard covers plugs with an integrated ground block, classes B and F, designed for continuous operating temperatures of 175 °C (or 125 °C). It is published by CEN following preparation by ASD‑STAN and is intended for consistent use across aerospace equipment and systems.

Key topics and requirements

  • Connector type: Rectangular, modular plug (size 2) with ground block for disconnect applications.
  • Operating temperature: Continuous rating of 175 °C (alternative 125 °C) - part of the high‑temperature EN 4644 series.
  • Classes: Defined for class B and class F shell variants (see EN 4644-002 for shell class definitions).
  • Physical dimensions & panel cut‑out: Detailed layout, dimensional drawings and recommended panel cut‑out are specified (figures referenced in the standard). Typical mounting uses 4 × 6‑32 UNC threaded holes; screw head max diameter 7.5 mm.
  • Mass limit: Maximum mass 75 g.
  • Housing types: Provision for housing variants, for example:
    • A: panel rear mount with 4 × 6‑32 UNC threaded holes
    • B: no mounting holes
  • Designation / identification: Standardized product ID format (example: EN 4644-023BAX) including shell class and polarization codes (polarization and contact arrangements addressed by EN 4644-002).
  • Normative references: Relies on EN 4644-001 (technical specification) and EN 4644-002 (performance and contact arrangements); matching receptacles specified in EN 4644-024 / -025 / -026.

Applications and users

EN 4644-023 is intended for designers, manufacturers, integrators and procurement specialists in the aerospace and defence sectors who need standardized, high‑temperature, modular connector plugs for aircraft or spacecraft electrical and optical systems. Typical uses:

  • Disconnectable power, signal and fiber optic connections in aircraft and avionics installations
  • Harness and panel interfaces requiring a ground block and defined mechanical/panel cut‑outs
  • Supplier product specifications, procurement, qualification and interchangeability tests
  • Test labs and certification bodies validating connector mechanical fit and conformance

Related standards

  • EN 4644-001 - Technical specification for the connector family
  • EN 4644-002 - Performance and contact arrangements (shell classes, polarization)
  • EN 4644-024 / EN 4644-025 / EN 4644-026 - Matching receptacle product standards

EN 4644-023 supports interoperability within the EN 4644 connector family and helps ensure consistent mechanical, thermal and mounting characteristics for aerospace rectangular modular connectors.
