YF6 Circular Umbilical Connector

  • Push-pull coupling mating and threaded coupling mating.
  • Mechanical demating or electromagnetic demating.
  • The mating is aligned by key to avoid mis-mating.
  • Its features resistant to high-intensity vibration and impact.
  • Widely used in strategic and tactical weapon systems, space launch systems, and between them and ground equipment.
  • Per ZZR-Q/Ag 1.063B-2000 (Military Grade YF6-57)
