Overview

EN 3645-012:2006 is a CEN product standard in the Aerospace series that defines the characteristics of a specific family of circular electrical connectors: lanyard release plugs with grounding fingers (shielding rings) - Type 2, shell size 25. These are scoop‑proof, triple‑start threaded coupling connectors rated for continuous operating temperatures of 175 °C or 200 °C in the series. The standard applies to the Model W style (see Table 2) and declares interchangeability with model W of MIL‑DTL‑38999/31.

Key topics and requirements

  • Connector type and scope
    • Releasable plug with lanyard release and grounding fingers (shielding ring), Type 2, shell size 25, equipped with male contacts.
  • Design and dimensions
    • Dimensional drawings and tolerances are provided in millimetres (see figures/tables in the standard).
  • Materials and surface treatment
    • Material and finish requirements (Model W example: cadmium‑plated aluminium alloy; salt spray resistance 500 h; crimp contacts; maximum operating temperature specified for model).
  • Electrical, mechanical and climatic performance
    • Performance and contact arrangement requirements are referenced to EN 3645-002.
  • Marking and designation
    • Identification, product marking and designation rules follow EN 3645-001 with example coding for model, shell code, contact arrangement and polarization.
  • Interchangeability
    • Connectors are derived from and interchangeable with MIL‑DTL‑38999/31 (model W), aiding cross‑sourcing and compatibility.

Practical applications

  • Use in aerospace wiring harnesses and avionics where:
    • High temperature resistance and robust mechanical coupling are required.
    • Rapid, fail‑safe removal via lanyard release is needed for maintenance or modular line‑replaceable units.
    • Effective electromagnetic shielding/ground continuity is required using grounding fingers/shielding rings.
  • Suitable for aircraft, helicopter and space vehicle electrical systems, especially in high‑temperature or harsh environmental zones.

Who would use this standard

  • Aerospace connector manufacturers and designers (product development, qualification)
  • Aircraft systems engineers and harness designers (specification and procurement)
  • Maintenance, repair and overhaul (MRO) technicians (replacement and compatibility checks)
  • Procurement and quality assurance teams (acceptance criteria, interchangeability)
  • Certification bodies and systems integrators requiring standardized connector interfaces

Related standards

  • EN 3645-001 (technical specification)
  • EN 3645-002 (performance & contact arrangements)
  • EN 3645-003 / -004 / -005 / -007 / -009 / -010 (receptacles, covers)
  • MIL‑DTL‑38999/31 (interchangeability reference)
