MIL-C-26482 Double bayonet DB-MCF series


Hermetic Sealing double bayonet DB-MCF series (Double Bayonet Multi Contact Feedthrough) are available with commercial bayonet style connections on both ends (air & vacuum side).

This special configuration provides a fast and easy connection even on the vacuum side, saving operating time.

Our own special sealing process, with the use of high quality techno polymer as insulator, gives superior electrical insulation and ultra-high vacuum tightness.

The feedthroughs are highly resistant to thermal and mechanical shocks.
