TECHNICAL FEATURES
800 AMP ROTARY GROUND SERIES
- Rated to 800 amps DC continuous at 100% duty cycle
- Provides consistent and stable current without fluctuation
- Maintenance-free without routine grease, cleaning, or brush replacement
- Sensitive environment, non-mercury rotary ground (RoHS) versions available
ROTOCON ERG-800 rotary grounds are rated for 800 amps continuous, ensuring stable, consistent current delivery in rotating applications without fluctuation, regardless of position, speed, orientation, or total revolutions. As a superior alternative to traditional metal-on-metal rotary grounds, including the Tweco RG-240, Lenco LRG-240, and similar solutions, ROTOCON ERG-800 rotary grounds offer greater durability, reliability, and long-term performance.
Designed for rotary welding, electroplating, electropolishing, cutting, and other high-current industrial applications, ROTOCON ERG-800 rotary grounds feature four versatile mounting configurations for easy integration. Unlike brushed and metal-on-metal contacts, ROTOCON rotary grounds are brushless and maintenance-free, eliminating the need for brush replacements, adjustments, or grease application. Built for demanding industrial environments, they are constructed from high-performance materials to ensure long-lasting, trouble-free operation.

General Specifications
ERG-800 Rotary Ground Specifications
AMPERAGE
800
AMPS CONTINUOUS DC
Amperage refers to the continuously rated current specification of the product at direct current (DC) to low/common frequency levels (<120 Hz).For elevated current, temperature, or frequency applications - please contact Meridian Laboratory for more information.
CONTACT RESISTANCE
<0.03mΩ
Contact resistance refers to the electrical resistance between the stationary and rotating portions, internal to the ROTOCON rotating electrical connector. This is measured without additional cabling or connectors, and is internal to the units themselves. This is measured stationary or rotating, regardless of rotational direction, speed, or orientation.
DUTY CYCLE
100%
CONTINUOUS
Duty cycle refers to the duration of time at which the ROTOCON slip ring can operate within a maximum specified condition. Not all ROTOCON slip ring and rotary grounds are tested or guaranteed while in an absolute maximum condition of all specifications (rotational speed, amperage, etc.) simultaneously. For more information or application specific questions, please contact Meridian Laboratory.

APPLICATIONS & USES
Common Uses for ERG-800 Rotary Grounds
Rotary Welding & Cutting
Tanks, pipes, and other rotary welding applications require a rotary ground to maintain a stable current transfer while materials rotate during welding, enabling the production of stacked tubes and other welded components. Similarly, welding tables, positioners, and robotic welding systems rely on a consistent, reliable current transfer to ensure precision and quality while the workpiece or welder rotates or moves.
Rotational Plating & Polishing
During electroplating or electropolishing, parts are often rotated in the bath to ensure even coverage and a high-quality finish. Rotary grounds play a crucial role by delivering a steady, consistent electrical current to the workpiece or fixture throughout the rotation process.
Rotary Sputtering & Deposition
Rotating electrical grounds are essential in sputtering applications, providing a ground circuit for the rotating workpiece to ensure uniform material deposition onto the substrate. Maintaining stable ground resistance enhances process consistency and precision, leading to a higher-quality finished product.
