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 plat-
ing 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
intermount with various existing MIL-spec box or wall mount re-
ceptacles, 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 avail-
able; 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 con-
tacts.
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 characteristics
provides durable protection to the contacts. The socket contacts
are probe proof, and all contacts are rear removable. 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 pat-
terns are also available with larger contacts in sizes 4 and 0.
