YF9 Circular Rainproof Umbilical Connector

Push-pull coupling mating and mechanical demating.
The mating is aligned by key to avoid mis-mating.
Its features compact size, lightweight, rainproof, dustproof.
It can withstand instantaneous high temperature of 850℃.
Widely used in the inter-stage electrical wiring mating of strategic and tactical weapon systems and aerospace launch systems, as well as the electrical mating between systems and ground equipment, and other industrial equipment.
