Asiantool A1M2 NM Single Conductor

The most compact single-pole non-mercury rotating connector in the Asiantool catalog, designed for high-speed signal integrity and ultra-low power transmission (up to 2A). It is the definitive solution for applications where weight and space are at a critical minimum.

Description

The A1M2 NM is engineered for precision signal transmission in microscopic or high-speed assemblies. While standard slip rings use sliding carbon brushes that create friction, dust, and electrical “noise,” the A1M2 NM uses a liquid metal pool to maintain a constant, “wet” contact.

This results in an exceptionally low and stable contact resistance (< 1 mΩ), ensuring that sensitive sensor data, thermocouples, or communication signals remain clean and interference-free during continuous 360-degree rotation. Its negligible mass and ultra-low torque make it ideal for the most delicate high-speed instruments.

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-Miniature 1-Pole Design: Extremely small form factor (M2 size), perfect for micro-robotics and surgical tools.
  • Liquid Metal Technology: Delivers an ultra-stable connection with near-zero electrical noise, protecting high-speed digital and analog signals from jitter.
  • Maintenance-Free: No mechanical brushes to wear down or replace, ensuring a long operational life without the need for periodic cleaning.
  • Eco-Friendly (Non-Mercury): Uses Gallium alloy, making it safe for use in food packaging, medical equipment, and cleanroom environments (CE RoHS).
  • Very High Rotation Speed: Optimized for extreme RPMs (up to 3000 RPM), significantly higher than standard power-heavy models.
  • Near-Zero Torque: Requires negligible force to rotate, which is critical for high-precision spindles and micro-motors.

Applications

  • Micro-Robotics: Providing a reliable signal link for sensors located at the “end-of-arm” tooling in high-precision assembly bots.
  • Medical Devices: Used in rotating laboratory equipment, small centrifuges, and surgical tools.
  • High-Speed Micro Spindles: Providing grounding or signal paths for precision dental tools or micro-milling machines.
  • Drones & UAVs: Enabling reliable signal transmission through high-speed rotating gimbals or specialized sensor mounts.
  • Precision Sensors: Transmitting data from rotating thermocouples, strain gauges, and high-speed encoders in miniaturized testing environments.
