An ultra-compact, 3-conductor non-mercury rotating connector designed for high-speed applications. It is engineered for systems requiring an exceptionally stable, electrically “silent” connection for sensitive data, sensors, or low-current power in a small form factor.
The A3S is the “Small” or “Signal” variant of the 3-pole lineup. By replacing mechanical brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This eliminates the signal jitter (electrical noise) and physical wear debris that typically cause data errors or mechanical failure in traditional 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.
