Asiantool A8H Multi Conductor

A high-capacity, 8-conductor non-mercury rotating connector designed for systems requiring multiple simultaneous electrical paths. It is engineered to handle a mix of power, control signals, and data in a single, compact housing.

Description

The A8H is designed for industrial automation where electrical “noise” must be eliminated across multiple channels. 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 8 poles at all times, removing the signal jitter and carbon dust contamination that often lead to data errors in 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

  • 8-Pole Configuration: Provides 8 independent channels, perfect for 3-phase AC power plus ground and four dedicated signal lines (such as sensors or PLC triggers).
  • Liquid Metal Technology: Offers 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.
  • Stable Torque: Maintains a constant, low rotating torque (3500 gm-cm) throughout its life, regardless of rotation speed.
  • Superior Insulation: Features an insulation resistance of > 50 MΩ, ensuring signal separation and safety across all 8 conductive paths.

Applications

  • Robotic Arms: Providing the electrical umbilical for multi-axis robots where sensor and motor lines are required.
  • Packaging Machinery: Managing multiple sensors, heating elements, and motor controls on rotating carousels.
  • Heated Rollers: Delivering power to internal heaters while simultaneously transmitting temperature sensor signals.
  • Wind Turbines: Used in pitch control systems where multiple motor phases and sensor feedbacks must pass through a single axis.
  • Testing & Measurement: Routing multiple sensor signals from rotating test rigs to stationary data loggers.
