FQC series circular connectors can be useed in the water-proof place. We use the reliable cage clamp connection instead of the traditional wire spring. These connectors have the features of lower contact resistance, anti-libration, shock proof, water proof and strong seal etc. They are widely used for the electrical connection between electrical equipment. Meet CE, RoHS. It can be interchanged with FQ series.
