Asiantool A4H NM Multi Conductor

Description

The A4H NM is a versatile solution for rotating systems that require a reliable power or signal interface. With 4 independent poles, it is perfectly suited for 3-phase power + ground or single-phase power + 2 signal lines.

By using liquid metal technology instead of mechanical carbon brushes, the A4H 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 transmitting sensitive sensor data or high-speed PLC communications alongside main power.

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

4-Pole Configuration: Consolidates up to four independent power or signal lines into a single compact housing.
Liquid Metal Technology: Ensures an ultra-stable connection with near-zero electrical noise, protecting sensitive electronics from interference.
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, making it safe for global use in food processing, medical, and environmentally regulated industries (CE RoHS).
High Current Capacity: Each of the 4 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.
