Mercury unused! Introducing a case of a new structure rotary connector!
We would like to introduce a case study and structure of a rotary connector developed by Hisawa Giken that does not use mercury. This product enables compact rotary connections for high currents. It is compliant with RoHS, has low contact resistance, low noise, low rotational torque, and a long lifespan. Additionally, it can operate in high-temperature and vacuum environments, which were not possible with conventional products. Our company can design connectors that meet specific requirements, including multi-pole, high-temperature, and vacuum environments. 【Features】 ■ Compact rotary connection for high currents ■ RoHS compliant with low contact resistance, low noise, low rotational torque, and long lifespan ■ Compatible with high-temperature and vacuum environments *For more details, please refer to the PDF document or feel free to contact us.

Company information
We are a development-oriented company that designs and develops a unique rolling-type rotary connector, which differs from conventional slip rings and mercury types, and we are continuously working on their improvements. The rolling-type slip ring features a one-of-a-kind structure globally, with low contact resistance, low noise, and low rotational torque. It is also capable of conducting high-frequency currents of 13.57 MHz, and we have numerous delivery records to major semiconductor manufacturers. To engage in development in a better environment, we relocated our office to the current location in May 2024.
