About
The MIL-DTL-38999 Series IV circular connector uses breech-lock coupling for ultra-fast mating and unmating in high-density environments. It includes hermetic seal variants for pressurized enclosure applications.
Series IV is favored when rapid connection and disconnection cycles are required. Hermetic variants with electrodeposited nickel on stainless steel provide gas-tight sealing for hermetic housings.
