Copper gold-plated material: stronger conductivity and ductility, better stability, wear resistance and corrosion resistance Tool usage: Recommend to use ST2163 or ST2169 (ACT-HDT) crimp tool KIT for crimping. Specially designed indenters that guarantee pull-out force. The cycle controlled precision ratchet assures the consistency of impression and the crimping quality of wires and contacts. Plug force test: the plug force is stable, can adapt to medium and high intensity vibration, and has high safety. The electrical connection is uninterrupted to ensure stable function. Connector Series: HD30 Series, HDP20 Series, DRC Series, HD10 Series, DT Series, DRB Series, DTV Series, AEC Series, STRIKE Series, Jiffy Splice
