High quality compatible with a water depth of 300m (30 atmospheres) and a durability of 10,000 attachment and detachment cycles! Added a power layout compatible with 38mm2 cables.

In addition to 4-core and 7-core options, the single-core power layout has finally been commercialized. The cumbersome potting process is unnecessary, and the push-pull coupling method makes handling easy. The open-face seal structure prevents water from entering the connector even in a non-coupled state. It has achieved a durability of 10,000 mating cycles. 【Applications】 Submersible pumps, ROVs, underwater lighting, marine-related facilities (buoys, etc.), underwater cameras, underwater defense equipment, railway-related applications. *You can view the product catalog by downloading the PDF below.

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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
