A weldable cres shell for permanently sealed pressure and vacuum housings where no elastomer can be tolerated Because the hermetic shells use a glass-fused insert, the contact tail is a solder cup, eyelet or PCB feedthrough rather than a removable crimp contact, and a weldable CRES shell for permanently sealed pressure and vacuum housings where no elastomer can be tolerated. Mating is the standard Series IV 90° quarter-turn breech-lok, so these receptacles mate with any D38999/46 or D38999/47 Series IV breech plug.
