Asiantool H43016 Through Bore Multi Conductor (16.2mm)

Description

The H43016 is the 4-pole version of Asiantool’s medium-bore lineup. Unlike traditional slip rings that use sliding carbon brushes—which generate friction, heat, and electrical “noise”—the H43016 uses a pool of liquid metal to ensure 100% surface contact at all times.

This results in an exceptionally low and stable contact resistance (< 1 mΩ), making it ideal for transmitting sensitive sensor data, high-speed communication, or stable power without the signal jitter or voltage drops associated with mechanical wear.

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

16.2mm Through-Bore: Sized to slide over standard 16mm industrial shafts, allowing for integrated mechanical and electrical rotation.
4-Pole Configuration: Provides 4 independent channels, perfect for DC power (+/-) plus two signal lines, or 3-phase AC power plus a ground/neutral.
Liquid Metal Technology: Offers zero maintenance and a significantly longer lifespan than brush-type connectors, with no carbon dust or debris.
High Signal Integrity: The liquid interface eliminates electrical “chatter,” making it suitable for Ethernet, PLC, and sensitive analog signals.
Eco-Friendly (Non-Mercury): Uses a safe Gallium alloy, ensuring RoHS compliance for food-grade, medical, and high-tech manufacturing.
Robust Housing: Built to withstand industrial vibration while maintaining precision electrical contact.

Applications

Rotary Indexing Tables: Providing power and signal to rotating carousels where the center is occupied by a 16mm drive shaft.
Packaging Machinery: Powering rotating heat-sealers and sensors on high-speed capping or filling lines.
Robotic Pivots: Passing electrical lines through the hollow centers of robotic arm joints or gimbals.
Wind Turbines: Transmitting blade pitch control signals and power from the hub to the nacelle.
Automated Assembly: Handling precise signals in rotating pick-and-place or testing tools.
