YF6A 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, impact, moisture-proof, salt spray-proof, mildew-proof, and dust-proof
  • Widely used in strategic and tactical weapon systems, space launch systems, and between them and ground equipment.
  • Per Q/Ag1.063.3-2014 (67 Pin), Q/Ag1.063.4-2014 (61 Pin)
