Industrial Waterproof Connector

The SZCNT56 series industrial waterproof connector is designed with reference to the US military standard MIL-C-26482 Series I (equivalent to the domestic GJB598A-1996 Series I). It is fully compatible with the same type of products produced by other companies. Its connection method adopts bayonet connection, and the contact termination form is crimping, welding or board connection. The product has the characteristics of quick connection, good shielding, high-level sealing, good salt spray resistance, and strong and reliable structure. It is suitable for electrical connection of electronic equipment such as new energy vehicles, communications, ships, engineering machinery, building automation and control, instrument measurement, energy and electricity, robots, machine tools, telecommunications data infrastructure, etc.
