Asiantool A8H NM Multi Conductor

Description

The A8H NM is a versatile multi-conductor solution for systems that need to transmit more than just standard 3-phase power. With 8 independent poles, it can easily handle a combination of 3-phase power, neutral, ground, and multiple control or sensor signals in a single compact housing.

By using liquid metal technology instead of traditional carbon brushes, the A8H NM maintains a constant “wet” contact with an extremely low resistance of < 1 mΩ. This eliminates the electrical noise, carbon dust, and mechanical wear associated with standard slip rings, making it ideal for high-speed data transmission and sensitive PLC communications.

Brand

Asiantool

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.

Features

8-Pole Multi-Channel: Allows for the consolidation of power and data lines (e.g., 3-phase power + 4 signal lines + Ground).
Liquid Metal Technology: Ensures an ultra-stable connection with near-zero electrical noise, protecting high-speed data and sensitive sensors.
Maintenance-Free: No brushes to wear down or replace, and no periodic lubrication required for the life of the unit.
Eco-Friendly (Non-Mercury): Uses Gallium alloy, ensuring the device is safe for global use and meets CE RoHS environmental regulations.
High Current Capacity: Each of the 8 poles is rated for 30A, allowing for substantial power transfer.
Low Rotating Torque: Requires minimal force to rotate, reducing the mechanical load on the system’s drive motor.
