Asiantool A4H Multi Conductor

A versatile, 4-conductor non-mercury rotating connector designed for industrial applications requiring multiple electrical paths. It is engineered to handle a mix of power, control signals, and data in a single, compact housing

Description

The A4H is designed for environments where electrical “noise” and signal degradation cannot be tolerated. By replacing mechanical brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact for all 4 poles at all times, removing the signal jitter, friction, and carbon dust contamination associated with traditional slip rings.

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: Ideal for 3-phase AC power plus ground, or two independent DC circuits (+/-).
  • Liquid Metal Technology: Provides zero maintenance and a significantly longer lifespan than brush-type connectors, as there are no parts to wear down.
  • High Signal Integrity: The liquid interface is electrically “silent,” making it ideal for sensitive analog sensors, high-frequency signals, and PLC communication.
  • Eco-Friendly (Non-Mercury): Uses a safe Gallium alloy, ensuring RoHS compliance for food-grade, medical, and high-tech manufacturing.
  • Low & Stable Torque: Requires minimal force to rotate (2000 gm-cm), which reduces the mechanical load on drive motors and prevents premature wear.
  • Superior Insulation: Features an insulation resistance of > 50 MΩ, ensuring signal separation and safety across all 4 conductive paths.

Applications

  • Heated Rollers: Delivering power to internal heaters while simultaneously transmitting a dedicated ground or sensor signal.
  • Packaging Machinery: Managing sensors, heating elements, and motor controls on high-speed rotating carousels.
  • Robotic Joints: Providing a reliable electrical link for rotating robotic axes where multiple control lines are required.
  • Wind Turbines: Used in pitch control systems where motor phases and sensor feedbacks must pass through a single axis.
  • Indexing Tables: Providing power and data to rotating workstations in automated assembly lines.
