Kyocera Corporation (President and CEO: Hideo Tanimoto, hereinafter referred to as “Kyocera”) is pleased to announce that, through joint research with the Japan Aerospace Exploration Agency (hereinafter referred to as “JAXA”), it has developed two new products: a 100A current feedthrough terminal that ensures durability and airtightness in liquid hydrogen environments while also handling high currents; and the MS-8 pin terminal, a hermetically sealed connector that can handle up to 110A for the entire connector.
These two products (hereinafter referred to as “the Products”) can be used for current input in equipment requiring high-power supply and extraction, such as pumping and discharge pumps for storing and transporting liquid hydrogen, as well as booster pumps and generators.
Kyocera developed the MS-10 pin terminal, a hermetically sealed connector for liquid hydrogen for measurement and control applications, in cooperation with JAXA and announced it in March 2024. This product also underwent demonstration testing for durability and airtightness in a liquid hydrogen environment at JAXA’s Noshiro Rocket Test Site, confirming its reliability. The development of the MS-8 pin terminal, a high-current compatible current input terminal and hermetically sealed connector that can be used in a liquid hydrogen environment, is the world’s first *1 .
