  • Military-Grade Versatility: MIL-DTL-38999 Series III in Square Flange (20), Jam-nut (24), and Plug (26) styles.
  • Superior Protection: IP67-rated waterproof seal; built to resist extreme shock, vibration, and harsh conditions.
  • Temperature Resilience: Reliable performance from -65°C to +200°C (Nickel) or +175°C (Cadmium) for high stability.
  • Advanced EMI Shielding: Rugged aluminum alloy shells provide 360° EMI shielding with Nickel or Cadmium finishes.
  • Installation Efficiency: Includes copper alloy crimp contacts and tools for rapid assembly and field maintenance.

Previously known as MIL-C-38999, MIL-DTL-38999 connectors come in four series: Series I, Series II, Series III and Series IV. They are environmentally resistant connectors that use removable crimp contacts and have an operating range of -65 to +200°C.

Series I connectors are bayonet coupled and have high-vibration properties. They are scoop proof and are ideal for heavy wind and moisture environments. They are utilised when a fast disconnect coupling system is required.

Series II connectors are bayonet coupled, are non-scoop proof, and have a low profile, so are used when weight or space is limited, or in low-vibration, high moisture, and strong wind situations.

Series III connectors are coupled by a quick screw Tri start thread, are scoop proof, and are best suited for normal mating and unmating applications and can be used in high temperature, moisture, wind, or vibration environments when used with the correct accessories. Series III connectors are most commonly use in Aerospace designs.
