Amphenol Tri-Start Subminiature Cylindrical Connectors
MIL-DTL-38999 Series III
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.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)
. Corrosion Resistance
- available in standard MILDTL-38999 olive drab cadmium (175°C) and electroless nickel plating (200°C), both withstanding 2000 hours of salt spray exposure. The base material is able to withstand an indefinite exposure to salt spray.
. Durability
- 1500 couplings minimum (in reference to connector couplings, not contacts)
. Extended Life Contact - Mil-approved plating process which provides 1500 couplings minimum. The latest offering from Amphenol in MIL-DTL-38999, the CLUTCH-LOK connector offers:
All advantages
of stainless steel/Class K firewall Tri-Start connectors plus a unique clutch design that actually tightens itself under vibration. Features include:
. High degree of differential torque
. No settling back to the next ratchet tooth
. Completely intermateable with all existing MIL-DTL-38999 Series III connectors
. Offers advantage in inaccessible, hard to reach areas where mating torque is
difficult to apply and complete coupling is not verifiable by inspection.
