Asiantool A2S NM Multi Conductor

Description

The A2S NM is the “signal specialist” in the 2-conductor family. In traditional slip rings, sliding carbon brushes create friction, debris, and electrical “noise” that can distort data. The A2S NM uses a liquid metal pool to maintain a constant, “wet” connection.

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.

Brand

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

Compact 2-Pole Design: Smallest form factor for 2-wire setups, ideal for tight mechanical assemblies.
Liquid Metal Technology: Delivers an ultra-stable connection with near-zero electrical noise, protecting high-speed digital and analog signals.
Maintenance-Free: No mechanical brushes to wear down or replace, and no lubrication required for the entire lifespan of the unit.
Eco-Friendly (Non-Mercury): Uses Gallium alloy, making it safe for use in food packaging, medical equipment, and environmentally regulated industries (CE RoHS).
Low Rotating Torque: Requires very little force to rotate, which minimizes the load on small drive motors and delicate rotating parts.
High Frequency Capability: Supports signal transmission up to 20 MHz, suitable for various digital communication protocols.
