D38999 Hermetic Connector
Overview
Hermetic = Airtight
Glenair is Qualified to MIL-DTL-38999
Series I, II, III and IV
Definition of a Hermetic
Connector
 Permanently sealed by fusion or other means to prevent the
transmission of air, moisture vapor, and all other gases. (Made
airtight by fusion or sealing)
 Hermeticity is usually expressed as the rate of leakage volume
of helium per second in time
 Glass-to-metal seal technology is used to provide a robust
hermetic seal between a metal conductor and a metal body. The
glass also acts as an insulator between the body and the pins.
 Complete isolation of all elements between two environments
