Twist Pin Contact Technology
The foundation of ITT’s Cannon Micro Connector portfolio
starts with ITT’s innovative twist pin contact system. This sys-
tem was originally developed in the early 1960’s and ITT was
one of the original interconnect companies to license this
technology and improve it. Our forty five years of experience
in manufacturing and establishing a fully automated manufac-
turing system for this contact has truly given ITT the foremost
knowledge in twist pin contact technology.
As the core of our micro products, the twist pin contact offers
a superior electrical and mechanical system that outperforms
traditional machined or stamped electrical contract systems.
ITT’s twist pin system consists of the Micro Socket and the
Micro pin or Twist pin. Figure I show the basic contacts.
Figure 1
The twist pin contact system consists of several stranded
cores making up the wire bundle. The strands are subse-
quently heat treated and a weld is performed on the tip of
each contact. Crimp sleeves are then inserted over the con-
tact and crimp areas are defined to produce a seamless crimp
system. The entire twist pin system is referred by ITT as a
Pos-A-Line contact alignment system. Our reference to this
system identifies that the flexible twist pin is recessed into the
insulator and the rigid socket is exposed thus reversing the
traditional positions of the pin and socket. During the mating
sequence, the socket is guided into the pin insulator by the
lead-in chamfer. The pin is kept from flexing beyond the sock-
et capture radius by the walls of the cavity. The hemispherical
weld of controlled radius at the tip of the pin combines with
the lead-in chamfer of the socket contact and the pin insula-
tor to cam the pin in alignment. ITT has developed a very
robust Six Sigma manufacturing process that controls the
welding process as well as the dimensions of the socket con-

The flexible twist-pin is recessed into the insulator and the rigid socket is
exposed, reversing the traditional positions of pin and socket. During mating, the
socket is guided into the pin insulator by the lead-in chamfer. The pin is kept
from flexing beyond the socket capture radius by the walls of the cavity. The
hemispherical weld of controlled radius at the tip of the pin combines with the
lead-in chamfers of the socket contact and the pin insulator to carn the pin into
alignment. By controlling the welding process and the dimensions of the socket
contact and the insulators, it is impossible for the recessed pin to escape the
socket capture radius.

that makes it impossible for the recessed pin to escape the
socket capture radius. Figure 2 shows the twist pin features
as well as mating and severe misalignment conditions.
The advantages of ITT’s twist pin contact system are many
and have been field proven in the most demanding applica-
tions and environments for over forty five years. Some of
these advantages include:
• Seven points of electrical contact (Micro 0.050-inc & Centi
• Five points of electrical contact (Nano 0.025-inch
• Contact and crimp sleeve materials carefully optimized for
• Seamless crimp sleeves
• Multiple 4-indent wire crimps standard and smaller bore
• Standard integral tail & thru bundle micro pin contacts (high
• High mating cycles
• High current handling capabilities
• System qualification in numerous Aerospace, Defense
• Wide array of wire terminations
The advantages listed above are by no means inclusive of
ITT’s innovative product improvement processes. Moving for-
ward, ITT plans to introduce additional new product features
supporting enhanced twist pin contact performance.
