Hermetically sealed connectors
Concentric Twinax/Triax
Hermetic seals
prevent leakage
through the bulkhead from
inside
of the connector. Trompeter's miniature size hermeti-
cally sealed connectors include the feed-through BJ78HS, the
front mounted BJ77HS, the rear mounted BJ79HS and the
newly designed threaded BJ379HS. In the subminiature size we
offer the front mounted BJ157HS and BJ157FLHS (four lug
version). The BJ3150HS and BJ3150SHS offer a threaded rear
mount version with a safety wire option. These connectors are
designed for bulkhead mounting in vacuum chambers, or where
toxic and other gases are present. These connectors have leakage
rates of 1x10
-8
atm cc/second. The 150 Series have leakage rates
of 1x10
-6
atm cc/ second.
They all meet MIL-C-49142 specifications. Standard non-
hermetic connector types such as the BJ78 could leak between
the contacts and dielectrics. Hermetically sealed connectors can
be used in commercial, military, and industrial applications
where toxic gas maybe present. Hermetic connectors are highly
beneficial in reactors, gas/petro plants, oil drilling sites, liquid
test and measurement, and space applications. They are reliable
under the most severe atmospheric conditions.
