PA&E's 38999 mateable circular hermetic connectors combines Kryoflex® ceramic-to-metal sealing technology with ultra light-weight materials to create truly hermetic connectors. They use Beryllium Copper CDA Alloy 172/173 contacts and accept 24 to 30 AWG solid/stranded wire. These 38999 mateable connectors provide greater than 5,000 Megohms at 500 VDC when tested in IAW MIL-STD-1344, Method 3003. They have a leak rate of less than 1X10-9cc/sec Helium at 1 atmospheric differential pressure and have an operating temperature range of -65°C to 200°C.
