JF3-134ZK-02/TJ-02 Separation (Detachment) Electrical Connector

JF3-134ZK-02/TJ-02 Separation (Detachment) Electrical Connector

     The JF3-134ZK-02/TJ-02 series of separation (disengagement) electrical connectors are specialized electrical connectors, mainly used in aerospace, aviation, missiles, rockets and other weapon systems as well as various ground equipment. When the equipment is operating normally, these connectors transmit electrical signals and power. When separation is required (such as inter-stage separation, shedding of the cover, load detachment, etc.), they can achieve instantaneous and reliable automatic disengagement or mechanical separation.
