Heavy Duty Amphenol M39029/59-366 Connector Featuring Rapid Coupling and Superior Contact Protection
Amphenol Tri-Start Series III MIL-DTL-38999 Connectors
Product Overview
The Amphenol Tri-Start Series III MIL-DTL-38999 connectors are high-performance cylindrical connectors designed for general duty and severe environment applications. They meet or exceed MIL-DTL-38999 Series III requirements, offering advanced features such as rapid coupling via a triple-start thread, shell-to-shell or metal-to-metal bottoming, and improved EMI shielding. Available in metal (aluminum, stainless steel) and composite shell options, these connectors provide superior EMI/EMP shielding, contact protection, moisture resistance, and corrosion resistance. The Tri-Start family offers exceptional versatility with a broad portfolio including options for high vibration (CLUTCH-LOK), firewall capability, fiber optics, fail-safe lanyard release, and various contact types like shielded, coax, twinax, and PCB tails.
