A multi-conductor non-mercury rotating connector designed for high-voltage applications (up to 500V) with a versatile pole configuration. It is specifically engineered to handle a combination of high-current power and signal channels in a single, compact housing.
The A3V4S is part of Asiantool’s “V” series, which often indicates a variable or multi-channel capacity within a standardized form factor. By replacing mechanical brushes with liquid metal, the A3V4S achieves a contact resistance of < 1 mΩ, effectively eliminating electrical “noise” and signal jitter. This makes it suitable for high-frequency data, sensitive analog signals, and 3-phase power transmission simultaneously.
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.
