It is an underwater connector compatible with 600 bar that can be attached and detached in water!

With a maximum pressure rating of 600 bar, we offer a lineup that includes signal lines, power lines, and coaxial types. They can be easily used for various applications, including power, signals, and video. Moreover, they allow for underwater mating and unmating (wet mate). (*Please note that this is not live insertion/removal, so power cannot be supplied during mating/unmating or when not engaged.) Are you having trouble with the delivery time of underwater connectors? With the underwater rubber molded connectors from DWTEK, which we recommend, you can obtain them in a shorter lead time compared to other underwater connector manufacturers.

• Other Connectors

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.

[Speaker] Taigo Isobe, Senior Manager, Innovation Center, Innovation Technology Department, NTT Data Corporation [Key Lecture Content] Quantum computers are attracting attention as a new computational mechanism based on quantum mechanics, providing innovative solutions to complex and large-scale problems that have been difficult to handle with traditional classical computers. In this lecture, I will first overview the foundational technologies and current status of quantum computers, organize the application examples that have been highlighted in the financial and chemical fields, and then outline the potential in new application areas such as odor reconstruction, weather forecasting, and digital agriculture. I hope you will realize that quantum computers are not just an extension of computational technology but are expanding into diverse areas such as perception, environment, and human sensibility.
