MIL-DTL-38999 Series III Connectors

Amphenol MIL-DTL-38999 Series III Circular Connectors deliver high-performance capabilities for demanding general duty and harsh environment applications. Developed to operate under severe high temperature and vibration, the connectors feature rapid coupling via a Tri-Start™ thread, shell-to-shell, or metal-to-metal bottoming. Amphenol designed these connectors to provide an EMI shielding capability of 65dB minimum at 10GHz and corrosion resistance of up to 500-hour salt spray exposure. Amphenol MIL-DTL-38999 Series III Circular Connectors offer a rated current range of 1.5A to 5A, a temperature range of -65°C to +175°C, minimum insulation resistance of 5000MΩ, and a dielectric withstanding voltage of 1000VRMS. These rugged and highly reliable circular connectors are ideally suited for industrial, commercial air, military, C4ISR, and space applications.
