Amphenol® Tri-Start MIL-DTL-38999* Series III Connectors offer the highest performance capabilities for both general duty and severe environment applications. Meeting or exceeding MIL-DTL-38999 Series III requirements, the Tri-Start connector with standard metal shells (aluminum or stainless steel with several finish options) offers these features:

• EMI Shielding – solid metal to metal coupling, grounding fingers, electroless nickel plating, and thicker wall sections provide superior EMI shielding capability of 65dB minimum at 10 GHz
• Contact Protection – recessed pins in this 100% scoop-proof connector minimize potential contact damage
• Moisture Resistance – improved interfacial seal design helps prevent electrolytic erosion of contacts
• Corrosion Resistance – shells of stainless steel or cadmium over nickel plating withstand a 500 hour salt spray exposure
• Vibration/Shock – operates under severe high temperature vibration, through 200°C
• Firewall Capability – available in a stainless steel shell, class RK, RS
• Lockwiring Eliminated – unique, self-locking, quick coupling connector eliminates lockwiring
• Quick Coupling – completely mates and self-locks in a 360° turn of the coupling nut
• Inventory Support Commonality – uses standard MIL-DTL-38999 contacts, application tools, insert arrangements
• Electrostatic Discharge Protection (ESD) – protection for sensitive circuitry without diodes, varistors, etc., with the use of the Faraday Cage principal which shunts high voltage, high current discharge events
• Ground Plane Connectors – with metallic insert for common grounding of coax, triax or twinax contact outer shield
• Hermetic- air leakage limited to 1 X 10-7 cm3 per second optional
