Supports long-term use below 2000m underwater! Underwater connectors that can be used in harsh environments.

The "Surio Underwater Connector M Series" is a connector designed for long-term use at depths of up to 2000 meters below the water surface. The receptacle, plug, receptacle, and plug cap are made from high-strength bronze, providing corrosion resistance against saltwater, seawater, sand, mud, mineral water, deionized water, hydrocarbons, and more. The single waterproof connector with an outer cable sheath is used for power transmission, signal transmission, data communication, marine exploration, and mining applications underwater. The double waterproof (DE) connector with both outer and inner cable sheaths is developed specifically for cables designed for extremely harsh environments or to achieve high safety levels, and is used for electrical connections in manned submersibles and applications requiring double-armored cables. 【Lineup】 ■ Single waterproof with outer sheath - FED straight plug with screw/coupling connection - PCE inline receptacle ■ Double waterproof with outer and inner sheath - FDED straight plug - PCDE inline receptacle *For more details, please refer to the PDF document or feel free to contact us.
