MIL-C-26482 Power (3kV DC) double bayonet PDB-MCF series


Hermetic Sealing PDB-MCF series (Power-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.

The particular design provides an high voltage insulation (tested up to 4 kV DC), a feature not not found on other brands.

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 10, 19, 26, 32 pins

3, 6 and 41 pin available upon request and for minimum quantity
