BMASC
Kemlon BMASC glass sealed
feedthrus consist of a pin, a
ceramic insulator, a threaded
body, and glass, all sealed
togeather to make a hermetically
sealed electrical
connector. The ceramic
insulator reinforces the glass
and extends the insulation beyond
the threads on the body.
The ceramic insulator consists of
highly insulating 99% Aluminum
Oxide. The BMASC glass
sealed feedthrus use a rubber
"O" ring to make the
extrenal high pressure
seal. The
"O" ring is positioned
in the groove of the metal
body. When the feedthru is
screwed into the mounting bore,
the "O" ring is
squeezed in compression to make a
seal.
BMASC Kemtites have similar applications as the BMS and BMSC. BMSC Kemtites work well in oil systems or in vacuum systems. In the case of BMASC the vacuum may be on either side, but for high pressure the pressure must be opposite the threaded side. The temperature ratings of BMASC Kemtites are also determined by the temperature rating of the "O" rings.
