Asiantool A3H NM Multi Conductor

Description

The A3H NM is engineered for applications that require a robust 3-conductor connection, typically for 3-phase AC power or a combination of power and grounding. By using liquid metal instead of mechanical carbon brushes, the connector maintains a constant “wet” contact with an extremely low resistance of < 1 mΩ.

This technology eliminates the electrical noise, carbon dust, and physical wear associated with traditional slip rings. Because it is a “Non-Mercury” model, it is safe for use in global manufacturing sectors that have strict environmental regulations, such as food packaging and medical equipment.

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

3-Pole Configuration: Ideal for 3-phase power delivery or high-current 2-wire circuits with a dedicated safety ground.
Liquid Metal Technology: Ensures an ultra-stable connection with near-zero electrical noise, protecting sensitive PLC and data signals.
Maintenance-Free: No brushes to wear down or replace, and no periodic lubrication required for the entire lifespan of the unit.
Eco-Friendly (Non-Mercury): Uses Gallium alloy, ensuring the device is safe for global use and meets CE RoHS compliance.
High Current Capacity: Rated for 30A per pole, allowing for significant power transfer in a compact footprint.
Low Rotating Torque: Requires very little force to rotate, reducing the mechanical load on the system’s drive motor.
