ITT Cannon hermetically sealed GS connectors are
designed for applications where a vacuum, inert
gas, or a constant or controlled pressure is required
to eliminate adverse effects created by atmospheric
changes.
GS connectors are hermetically sealed with com-
pression glass to prevent air leakage in excess of
1 x 10^-5 standard cubic centimeters per second at
1 atmosphere. Standard hermetic receptacles are
available with either solder pot or eyelet contacts.
Tube-type contacts for special solid wire feedthru
applications (thermocouple) are also avaiable.
The standard material for shells and contacts is
steel with tin over cadmium finish on GS02 connec-
tors. Other materials and finishes can be supplied
to meet any specific application.
GS connectors are manufactured to ITT Cannon
specifications and meet the Instrument Service
Voltage Rating of MIL-C-5015. Connectors with
higher voltage ratings are also available upon re-
quest. Salt spray, shock and vibration requirements,
and mating dimensions all approximate the require-
ments of MIL-C-5015 and can be contractually
approved for military applications.
D*H - D Subminiature MIL-C-24308
D*H hermetically sealed connectors are designed to
meet environmental conditions of extreme pressure
differential. These connectors are part of the
ITT Cannon D subminiature series and are qualified
to MIL-C-24308. The hermetic seal prevents leak-
age and subsequent accumulation of corrosive
moisture behind the connector. There are five basic
shell sizes in both standard and thru-bulkhead
designs which can accommodate from 9 to 50
contacts. Polarization is achieved by the keystone
shape of the shell, a feature of all connectors within
the D Subminiature series.
Locking devices are available for all shell sizes. Size
20 pin contacts are standard and have a current
rating of 5 amps. † Eyelet, solder pot, and feed-thru
contact terminations are available and can accom-
modate stranded wire up to #20 AWG.Operating
temperatures range from -54˚C to 125˚C (-65˚F
to 257˚F).
Your inquiries are invited regarding custom brazed
component variations and special modifications.
†Military rating of #20 contacts or wires is 1.5 mps average, and
7.5 amps maximum.
MDMH - Microminiature MIL-C-83513
Contact Layout: 9, 15, 21, 25, 31, 37, 51, 100
Hermetic Micro Seris Mates with MDM
Rectangulars
MDMH Connnectors are ideal for applications requir-
ing an extremely small, hermetically sealed connec-
tor having a higher contact density then traditional
rectangular connectors. The MDMH receptacle has
from 9 to 100 socket contacts on .050' (1.27mm)
centers and mates with ITT Cannon MICRO Divi-
sion's MDM Series havign reliable, proven, "Twist
Pin" contacts. The connector utilizes size 24 con-
tacts that are compression glass-sealed through a
steel shell and into a "front-end" insulator. AN
interfacial seal provides environemental protection
when mated. MDMH receptacles are soldered to
achassis or container providing a completely leak-
proof unit.
Features:
Hermetically sealed connector designed for
those applications where a vacuum, inert gas, or
a constant controlled pressure are required to
eliminate advere effects created by atmospher-
ic changes.
Steel shells to provide greater strength, prevent
Chipping, cracking or breaking, offer electromag-
netic (EMI) and RFI shielding.
Silicone elastomer compression interfacial seal
to provide a moisture and humidity seal between
each contact and between contacts and shell.
