A high-capacity, 1-conductor non-mercury rotary connector designed for industrial power applications. It is engineered to handle substantial current loads while maintaining extreme signal stability and minimal heat generation.
The A1H25PS is part of the high-power “PS” series. By replacing traditional mechanical carbon brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact at all times, eliminating the electrical noise, friction, and carbon dust contamination that typically plague high-current mechanical slip rings.
Asiantool’s slip rings (rotating electrical connectors) utilize special insulation, sealing, and conductive technologies. In the first three to four years of our company’s establishment, we worked in the direction of developing multi conductor models for A8H, A6H, A4H and other relevant models. At the same time, our company’s research and development team has also developed a single conductor model for theelectrical plating of 250A-A1H25S. Now, we have upgraded the product quality and introduced multi conductor models for up to 14 poles of A1430 and single heavy current conductor models up to 7500 A. for mass production.
