Asiantool H43016 NM Through Bore Multi Conductor (16.2 mm)

Description

The H43016 NM is engineered for applications requiring the transmission of power or signals through a rotating shaft. The 16.2 mm through-bore allows the unit to be mounted directly onto a drive shaft or used as a conduit for pneumatic or hydraulic lines.

Unlike traditional slip rings that use carbon brushes—which create dust, wear out, and generate electrical interference—the H43016 NM uses liquid metal to maintain a constant “wet” contact. This results in an exceptionally low contact resistance (< 1 mΩ), making it ideal for sensitive sensor data, video signals, and high-frequency transmissions that require a clean, noise-free environment.

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.
