Asiantool A1M2 Single Conductor

The smallest 1-conductor non-mercury rotary connector in the lineup. It is engineered to transfer stable electrical power (up to 20A) or sensitive signals through a rotating interface with near-zero electrical noise.

Description

The A1M2 is designed for precision applications where space is extremely limited. By utilizing a liquid metal pool instead of mechanical brushes, it achieves a contact resistance of < 1 mΩ. This ensures 100% surface contact at all times, making it ideal for transmitting sensitive data or low-current power without the signal “jitter” or friction-induced wear common in mechanical contacts.

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

  • Ultra-Compact Design: The minimal footprint allows it to be integrated into small robotic joints, medical devices, or high-speed spindles.
  • High-Speed Capability: Rated for significantly higher RPMs than the heavy-duty “H” models, making it suitable for fast-spinning lab and testing equipment.
  • 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.
  • Minimal Torque: Requires extremely low force to rotate (150 gm-cm), ensuring it does not interfere with the precision of delicate high-speed drive systems

Applications

  • High-Speed Spindles: Maintaining a stable ground or signal connection for precision CNC or lab spindles.
  • Rotary Sensors: Providing a reliable electrical path for high-speed encoders or proximity sensors in automated lines.
  • Robotic Joints: Serving as a compact power or signal link for rotating axes in small-scale robotics.
  • Medical Equipment: Used in rotating medical imaging devices or lab centrifuges where “clean” signal transmission is vital.
  • Small Heated Rollers: Delivering power to small rotating heating elements in specialized packaging or printing machinery.
