Series III, TV Tri-Start Connectors, offer more versatility
& options than any other interconnection family!
High reliability and increased versatility best
describe Amphenol MIL-DTL-38999, Series III
circular connectors. Originally designed
for the harshest of environments and most
demanding of applications, Amphenol MIL-
DTL-38999 Series III, Tri-Start connectors
continue to evolve in pace with the needs of an
ever-changing market.
Amphenol Tri-Start connectors can be
configured with a number of application
specific technologies like Filters, Hermetics,
PC Tails, Fiber Optics, Flex, CLUTCH-LOK,
Fail Safe, and contacts. Flexibility aids in
design optimization through the combination
of different technologies within a common,
time-tested, harsh environment connector
body.

Performance
Designed for Performance
Numerous advantages in performance capability are designed
into the Amphenol Tri-Start Connector. A positive metal to metal
coupling design, grounding fingers, and elect­roless nickel plating
provide superior EMI shielding capabil­ity of 65 dB minimum at
10 GHz.
Acme threads provide coupling durability. Thicker wall sec­tions
and a greater coupling surface area improve strength and shock
resistance. Blunting of the thread on both the coupling nut and
receptacle eliminates cross coupling. The connector quickly mates
and self locks in a 360° turn of the coupling nut.
Elongated mounting holes permit the Tri-Start Connector to inter-
mount with various existing MIL-Spec box or wall mount recep-
tacles, giving it a design replacement advantage.
Shells of stainless steel, or cadmium over nickel plating pre­vent
severe corrosion. Resistance is tested through expo­sure to a 500
hour salt spray. Composite versions provide protection from salt
spray exposure for 2000 hours. Other finish options are available;
see how to order Tri-Start metal and Tri-Start Composite.
Recessed pins minimize potential contact damage in this
100% scoop-proof connector. In a blind mating application,
mating shells cannot “scoop” the pins and cause a shorting
or bending of contacts.
The design of the Amphenol Tri-Start interfacial seal meets
the MIL-DTL-38999 Series III requirements for electrolytic
erosion resistance.
A rigid dielectric insert with excellent electrical characteris­
tics provides durable protection to the contacts. The socket
contacts are probe proof, and all contacts are rear remov­
able. They are plated in the standard 50 micro inches
minimum gold, with 100 micro inches as an option, and
are available in standard Tri-Start insert arrangements and
special Pyle® insert arrangements in sizes 10 power, 12,
16, 20 and 22D con­tacts. Special insert patterns are also
available with larger contacts in sizes 4 and 0.
