A high-capacity, 1-conductor non-mercury rotary connector designed for systems requiring the transfer of significant electrical power (up to 250A) through a rotating interface.
The A1H25S is engineered for industrial environments where standard mechanical slip rings fail due to high heat, brush wear, and electrical arcing. By replacing physical brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact at all times, providing a stable, “noise-free” power transfer even at high rotation speeds.
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.
