XAVAC D-sub Hermetic feedthroughs for vacuum-Positronic

XAVAC D-sub feedthrough connectors are hermetic connectors for space and / or industrial vacuum applications.

Both sides of the d-sub feedthrough contain four threaded mounting holes, an o-ring groove and fixed female jackscrews. Consequently this allows either side of the connector to be mounted toward the vacuum, therefore giving the customer the ultimate in flexibility.

Positronic Xavac feedthroughs are filled with an epoxy resin making them far more resilient to vibration, shock and damage compared to glass ceramic alternatives.
