Twinax/Triax Connectors / Hermetically Sealed Connectors
Concentric Twinax/Triax
Hermetic seals prevent leakage through the bulkhead from inside
of the connector. Trompeter’s miniature size hermetically sealed
connectors include the feed-through BJ78HS, the front mounted
BJ77HS, the rear mounted BJ79HS and 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 have leakage
rates of 1x10-8 atm cc/second. The 150 Series have leakage rates of
1x10-6 atm cc/second.
These connectors meet MIL-C-49142 specifications. Standard non-
hermetic connector types such as the BJ78 could leak between
the contacts and dielectrics. Hermetically sealed connectors are
designed for bulkhead mounting in vacuum chambers or where
toxic and other gases are present. Hermetic connectors are highly
beneficial in reactors, gas/petro plants, oil drilling sites, liquid test
and measurement, commercial, military, industrial and space
applications. They are reliable under the most severe atmospheric
conditions.
