Greenwood can supply hermetically sealed connectors from the Trompeter range. Hermetic seals prevent leakage through the bulkhead from inside the connectors. Trompeter's miniature size hermetically sealed connectors include the feed-through BJ78HS, the front mount BJ77HS and the newly designed threaded BJ376HS. In the sub-miniature size, Trompeter offer the front mounted BJ157HS and BJ157FLHS (4-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 1 x 10`8 atm cc/second. The 150 series have leakage rates of 1 x 10`6 atm cc/second. Leakage rates are as measured at vacuum/1 bar. No tests over 1 bar have been carried out.

They are manufactured to 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 may be present. Hermetic connectors are highly beneficial in reactors, gas/petro plants, oil drilling sites, liquid test and measurement and space applications. Tested to 1 Bar, they are reliable under the most severe atmospheric conditions. Key features include:

• Glass to metal seals
• Sustains extreme temperature ranges
• Standard brass body
• Gold plated contacts
