Performance
Tri-StartTM MIL-DTL-38999 Series III
with Metal Shells - Aluminum, Stainless Steel, Class K Firewall Composite Tri-Start,
Qualified to MIL-DTL-38999, Rev. J
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:
• EMIShielding - solid metal to metal coupling, grounding ngers,
electroless nickel plating, and thicker wall sec tions 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 cad mium over
nickel plating withstand a 500 hour salt spray exposure
• Vibration/Shock - operates under severe high tempera ture
vibration, through 200°C
• Firewall Capability - available in a stainless steel shell,
class RK, RS
• Lockwiring Eliminated - unique, self-locking, quick cou pling
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 principle which shunts high voltage, high current
discharge events (see page 422)
• Hermetic- air leakage limited to 1 X 10-7 cm3 per second optional
• Qualified Specifications - Stainless Steel qualied to BACC63DB
and BACC63DC specications
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)
See Composite weight comparison chart on page 20.
• Corrosion Resistance - available in standard
MIL-DTL-38999 olive drab cadmium (-65°C to 175°C)
and electroless nickel plating (-65°C to 200°C), both with
standing 2000 hours of salt spray exposure. The base mate-
rial is able to withstand an indenite 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
• Qualied to BACC63CT and BACC63CU specications
The Tri-Start option CLUTCH-LOK offers all advantages
of stainless steel/Class K firewall for MIL-DTL-38999
Series III 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 difcult to apply and
complete coupling is not veriable by inspection
See page 29 for description, 22 – 24 for ordering.
