YF1N Type Circular Umbilical Connector

  • Push-pull coupling mating and threaded coupling mating.
  • The mating is aligned by key to avoid mis-mating.
  • Motor driven demating and pull rod demating.
  • The socket features sealing function.
  • It has filtering (anti-radiation), flame protection and shielding functions.
  • Widely used in applications involving the electrical mating and demating between electronic equipment on satellites and nuclear weapons and ground-based electronic equipment.
  • Per YF1N-48TD Q/Ag1.083-2000 (J Grade) (Z)-Q/Ag20832-2011 (Reliability Improved)
