• Positronic Hivac connectors are feedthroughs equipped with D-subminiature adapter connectors for space and industrial vacuum applications.
  • The Hivac connectors configuration requires three separate units to function properly. The centre unit is the feedthrough. This feedthrough requires two adapter units, one for the atmospheric side and one for the vacuum side.
  • Both sides of the feedthrough contain four threaded mounting holes and an o-ring groove. These redundant features allow either side of the connector to be mounted toward the vacuum, giving the customer the ultimate in flexibility..
  • All Hivac series connectors are 100% leak tested after fabrication
  • Insulator: Glass filled DAP per ASTM-D-5948 or polyester glass-filled per ASTM D 5927, UL94V0, ASTM E-595, NASA-RP-1124.
