Asiantool A2S Multi Conductor

An ultra-compact, 2-conductor non-mercury rotating connector optimized for high-speed rotation and sensitive signal integrity. It is the preferred choice for transmitting data or power in a small form factor where electrical “noise” must be eliminated

Description

The A2S is the “Small” or “Signal” variant of the 2-pole lineup. By replacing mechanical brushes with a pool of liquid metal, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact at all times, removing the signal jitter and physical wear debris that typically cause data errors or mechanical failure 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

  • 2-Pole Compact Design: Optimized for single-phase low power (Live/Neutral), DC circuits (+/-), or a dedicated signal/return pair.
  • High-Speed Capability: The “S” series is engineered for significantly higher RPMs than the heavy-duty “H” models, making it ideal for fast-spinning spindles.
  • Liquid Metal Technology: Provides zero maintenance and a near-infinite signal integrity lifespan because there are no physical brushes to wear down or replace.
  • Eco-Friendly (Non-Mercury): Uses a safe Gallium alloy, ensuring RoHS compliance for medical, food-processing, and laboratory environments.
  • Ultra-Low Torque: Requires minimal force to rotate (200 gm-cm), preventing mechanical drag on delicate high-speed drive systems.
  • Stable Contact: Maintains consistent electrical performance regardless of rotation speed, which is critical for sensitive analog sensors.

Applications

  • Thermocouples & RTDs: Transmitting precise temperature data from rotating shafts without thermal “noise” or signal degradation.
  • Rotary Sensors: Maintaining perfect signal timing for high-speed encoders and proximity sensors.
  • Strain Gauges: Delivering sensitive analog signals from rotating test rigs or spinning samples to stationary data acquisition units.
  • High-Speed Spindles: Providing power or monitoring signals to high-speed CNC or laboratory spindles.
  • Semiconductor Tools: Providing reliable data links in ultra-clean environments where carbon dust from brushes is prohibited.
