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% scoopproof 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 MILDTL-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 (see page 51) • Ground Plane Connectors - with metallic insert for common grounding of coax, triax or twinax contact outer shield (see page 49) • Hermetic- air leakage limited to 1 X 10-7 cm3 per second optional MIL-Qualified to MIL-DTL-38999, Rev. K, the Amphenol® Composite Tri-Start Connector offers a lightweight, corrosion resistant connector with the same high performance features as its metal counterpart. The Composite Tri-Start Connector also includes the following features: • Lightweight - 17% – 70% weight savings (17–40% weight savings vs. aluminum) (60–70% weight savings vs. stainless steel)
