MIL-C-26482 Standard S-MCF series


Hermetic Sealing standard S-MCF series (Standard Multi Contact Feedthrough) are available with commercial bayonet style connection on air side and threaded connection on vacuum side.

This standard configuration provides a typical connection, compatible with MIL-C-26482 standard.

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.


Available with 3, 6, 10, 19, 26, 32 and 41 pins upon request and for minimum quantity
