Overview

EN 4644-022:2015 is a CEN aerospace product standard that defines the size 2 plug (male connector) used for disconnect applications in the modular rectangular family of electrical and optical connectors with rectangular inserts. The series is intended for high-temperature continuous operation (175 °C or 125 °C) and covers mechanical interface, mounting and identification details for plugs in shell classes A, C and E. The matching receptacles are specified in EN 4644-024, EN 4644-025 and EN 4644-026.

Key Topics

  • Scope and purpose
    • Specifies the size 2 plug configuration within the EN 4644 modular rectangular connector family for aerospace use.
  • Operating temperature
    • Rated for continuous operation at 175 °C (or 125 °C) as stated in the series title.
  • Mechanical dimensions and panel cut-out
    • Includes required external dimensions and recommended panel cut-out (figures provided in the standard).
    • Panel fastener information: two screw heads with maximum diameter 6 mm (per figure note).
  • Mounting hole and thread options
    • Three housing types for mounting:
      • D - two clear holes Ø 3.09 mm min (3.20 mm max)
      • L - two 4-40 UNC threaded holes
      • F - two 6-32 UNC threaded holes
  • Mass
    • Maximum mass of the plug: 40 g.
  • Designation and identification
    • Designation format example: EN 4644-022ADX, where the code conveys standard number, shell class, housing type (D/L/F) and polarization according to EN 4644-002.
  • Normative references
    • Relies on series documents for technical specification and performance: EN 4644-001, EN 4644-002 and the corresponding receptacle parts (EN 4644-024/025/026).

Applications

  • Aerospace electrical and optical systems requiring modular, rectangular disconnect connectors rated for elevated continuous temperatures.
  • Use cases:
    • Aircraft wiring harnesses, avionics equipment panels and line-replaceable units (LRUs) where robust, high-temperature plug interfaces are required.
  • Typical users:
    • Connector designers and manufacturers, aerospace systems engineers, procurement/specification teams, qualification and test laboratories.

Related Standards
