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.

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.

More and more companies are trying to address the increasingly serious shortage of human resources through employee development. However, there are some concerns regarding effective training... ✓ We want to improve the skills of new and existing employees. ✓ There are no instructors or training know-how within the company. ✓ The cost of training is high and does not reach all employees. To address these concerns, "Human Resource Development Professionals, PC Assist Co., Ltd." and "Subsidy Professionals, Social Insurance Labor Consultant Corporation Management Center" will respond! We will thoroughly explain ways to secure human resources while keeping costs down. Please feel free to join us.

ES Waternet Co., Ltd. will exhibit at the 12th International Smart Agriculture Expo held at Makuhari Messe. We will showcase various products including the "Valve Remote Monitoring and Control System OMEGA," which allows for the setting, operation, and monitoring of irrigation programs, including various sensor controls, remotely via PC or smartphone through the cloud; the "Micro Fogger Set," ideal for cooling and humidifying with fine mist in greenhouses and livestock barns; and the "ES Nutrient Cultivation System," which packages automatic irrigation timers, solenoid valves, liquid fertilizer injectors, pressure control valves, air valves, and filters necessary for cultivation in greenhouses. We look forward to welcoming you to our booth.

When conducting structural analysis of organic compounds, IR, NMR, and MS can be considered the three sacred treasures. If the analysis is performed correctly, it is possible to elucidate the structure of even quite complex compounds. However, actual spectra are often not of a single compound, as seen in textbooks, which can lead to significant challenges in interpreting results for beginners in analysis. Additionally, while database searches are a useful tool in structural analysis, the ability to read spectra is necessary to select the correct structure from among the candidates, not just pattern matching. In this course, we will lecture on the basic ways to interpret IR, NMR, and MS spectra, including simple explanations of principles, points to be aware of during analysis, and how to proceed with actual analysis, incorporating some exercises as well.

We will be exhibiting at the "Livestock Materials EXPO" held at Makuhari Messe! We plan to showcase examples of our "Fermentation Drying Equipment for Livestock Manure," provide information on our "Composting Equipment and Deodorants," and introduce our "Subsidy Projects." Please feel free to stop by our booth. We will give a small gift to those who fill out our survey or have implemented our composting system! We look forward to meeting everyone. = Exhibition Information = Dates: October 1 (Wednesday) to October 3 (Friday), 2025, for three days from 10:00 to 17:00 Venue: Makuhari Messe, Halls 5-7, 9, and 10 2-1 Nakase, Mihama-ku, Chiba City Booth Number: Hall 9, 35-6
