Nano Miniature NDD Series Connectors
The Challenge
ICS’s top tier Micro connector customers approached ITT, Interconnect Solutions about a high density and robust low profile Nano
miniature connector that allowed more signal carrying capacity in a smaller package. In addition, these customers identified the need
to have these connectors perform in high shock and vibration environments as well as high temperature +200 degree C environ-
ments. These same customers requested the use of ITT’s standard twist pin contact system within this new form factor of products.
Standard hardware accessories featuring
jackscrew assembly option accommodating
increased functionality in user applications
Knurled Jack Screws for ease of mating
High temperature LCP dielectric material
providing wider range of operating capabili-
ties for hostile environments
Proven twist pin contact construction
with 5 points of electrical contact and high
reliability crimp joints yielding robust con-
tact performance
Thru hole PCB Mount with mating plug con-
nector accommodating placement directly
on printed circuit boards. SMT version avail-
able in the future
D
Multiple contact layouts from 9 to 51
positions, on 0.025 centers providing
greater variability in data transmission require-
ments
Cable Harnesses available in discrete
insulated wires, ribbon cable, and flex
circuit terminations
The ITT Solution …
Interconnect Solutions collated VOC information from multiple OEM’s manufacturing sophisticated electronics equipment for
Aerospace, Geophysical, and Industrial applications and correlated this input with market trend data for small form factor
connectors. Based on the strong VOC results and ITT's engineering expertise in designing and manufacturing micro miniature
connectors, ICS developed the dual row Nano Miniature NDD Series connector family. This new family of nano miniature
connector products addresses the harsh environments typically seen in our customers’ applications and provides higher density
signals within a smaller profile connector package.

Nano Miniature NDD Series Connectors
Technical Overview
ITT has been manufacturing harsh environment single row nano miniature connectors since 1971. The new NDD series from
ITT takes advantage of ITT’s over 35 years experience in nano miniature connector design to introduce a new level of innovative
higher density family of connector products. This new Nano Miniature NDD Series connector will be qualified to the new mil-
itary specification MIL-DTL-32139.
ITT`s NDD miniature connectors are small form factor high density interconnects designed and manufactured for high relia-
bility and harsh environment applications. These interconnects are ideal where size and weight limitations require an ultra low
profile and robust interconnect package. Utilizing our innovative twist pin contact system on 0.025 contact spacing and having
5 points of electrical contact, the NDD series offers an extremely rugged small form factor interconnect solution. Typical appli-
cations for the NDD series are Avionics, Aerospace, Defense Electronics, Geophysical, Industrial Control Systems, and Medical
Diagnostics.
Twist Pin technology
At the heart of ITT’s new dual row NDD series we've incorporated our proven twist pin contact system. The twist pin contact
system has been utilized exclusively for ITT’s larger MDM series of products for over 45 years.

Double Density D - .075" Contact Spacing
2D*D
Environmentally sealed Double Density D con-
nector offers superior vibration and moisture
resistant characteristics.
The connector features superior environmental
sealing which makes it suitable for any application
where severe environmental protection is critical.
The connector's contact density design was
achieved by using field proven, highly reliable
Centipin/Centisocket contacts on .075" centers.
Designed to maximize positive contact mating, the
contact positions are reversed, leaving the flexible
Centipin contacts recessed in the insulator while
the more ruggedized centisocket contacts are ex-
posed.
This reversal of positions and the chamfered-entry
of the sockets assures positive mating even under
severe conditions where misalignment of mismatch-
ing of the connector might occur.
High reliability and protection of the contacts is
