Hermetic Connectors
Users around the world have found that ITT Cannon
hermetic connectors function reliably under ex-
treme environmental conditions. Hermetic connec-
tors are impervious to most liquids and gases,
including acids, alkalis, oils, gasoline, jet fuel and
hydraulic fluids. They can take shock loads as high
as 100 g's with no loss of hermeticity, and can take
extremes of both heat and cold with no loss of
performance.
Manufacturing Expertise
Cannon compression glass seals are strong. A
50,000 psi compression stress generates a sealing
force that can withstand up to 10,000 psi differ-
ential pressure (pressure varies with connector
type). Since it is independent of adhesion, the seal
has a temperature capability of -260˚ to +600˚
Fahrenheit. The seal has high radiation resistance
and a leak rate of less than 10^-7cc per second.
All Cannon hermeti connectors are 100% tested
after fabrication. A stringent examination ensures
that all military specifications are met. The product
is tested for leak performance, dielectric with-
standing voltage and insulation resistance.
Custom Design Capabilities
Custom hermetic connectors can be manufactured
to meet special requirements. Hermetic connectors
have been developed to withstand exposure to
propellants, high pressure and high temperature
conditions for missiles, "sub-safe" connectors for
penetration feed-thru on ships and submarines,
connectors for aircraft engines, and space applica-
tions.
KPTH/PVAH - Miniature Circular MIL-C-26482
ITT Cannon hermetically-sealed KPTH and PVAH
(MIL-C-26482, Series I and II) connectors are
designed for those applications and environments
that require delicate mechanisms to be protected
from variations in atmospheric pressure (leakage is
less than 0.01 micron ft ³ /hr [10 ^-7cc/sec.]
The receptacles are available with pin contacts only
and in three shell styles; box mounting KPT02H,
solder mounting KPT01H, and jam nut KPT07H for
Series I; box mounting PVA0, solder mounting
PVA3, and jam nut PVA7 for series II. Contact
arrangements are tooled in a full leak-free com-
pression glass web.
KJLY, KJY, KJAY - Miniature Circular MIL-C-38999 Series I, II, III
Cannon's KJLY/KJY/KJAY miniature circular con-
nectors are hermetically sealed and designed to
meet the critical performance and design require-
ments of MIL-C-38999 (leakage is less then 0.01
micron ft ³ /hour [10^-7 cc/sec.]). Engineered for high
density circuitry capabilities, these connectors are
designed to operate at temperatures ranging from
-85˚F to +392˚F (-65˚C to +200˚C); solder
mounts 302˚F (150˚C). They are readily adaptable
to both commercial and space age requirements
where size, weight, scoop proof/low-profile design
and high reliability are key factors. KJLY/KJLY/
KJAY connectors are offered in nine shell sizes. A
total of 53 contact arrangements are available that
will accommodate from 3 to 128 contacts using
AWG wire sizes 16 through 28. Contacts are of
nickel/iron alloy with gold plated finish.
BFH/TBFH - Standard Circular MIL-C-5015
TBFH-100/TBFH-200
TBFH-110
The BFH is a hermetically sealed version of the BFR
bulkhead fitting.
The TBFH-100 is a jam nut-mounted, thru-bulkhead
receptacle for panel thicknesses of .187" thru
.312". Sealing against the bulkhead is accom-
plished by and O ring seal.
The TBFH-200 is similar to the TBFH-100 with a
longer overall length for panel thicknesses of .375"
thru .750"
The TBFH-110 is the hermetically sealed version of
the TBF thru-bulkhead receptacle. It is flange
mounted and mates with 3106, 3107 and 3108
plugs. Contacts are sealed to achieve hermeticity
preventing air leakage in excess of one micron cubic
foot per hour (10^-7 cc/sec.) at a pressure differ-
ential of one atmosphere. Receptacles with leakage
rate of 0.01 micron cubic foot per hour (10^-7
cc/sec.), and lower, are also available.
Contacts and shells are steel. Standard finish is
clear chromate over cadmium. Other finishes are
available for high temperature and special applica-
tions.
Dimensions are shown in inches (millimeters).
