ROTOCON High Current Rotary Grounds | ERG Series

• Provides stable and consistent current
• Does not require grease, adjustment, or maintenance
• Unaffected by total number of revolutions or rotation
• Standard models and custom solutions
• Non-mercury rotary ground (RoHS) models available

Meridian Laboratory's ROTOCON ERG Series of brushless rotary grounds are designed to mount at the end of a workpiece and provide a low resistance rotating ground path.  ROTOCON brushless rotary grounds provide stable and consistent current delivery with no changes or fluctuation in amperage over time regardless of orientation, total revolutions, or instantaneous speed.

All ROTOCON brushless rotating grounds are environmentally sealed and use robust and corrosion resistant materials that ensure a long service life without the maintenance and grease required by conventional, metal-on-metal rotary ground manufacturers such as Tweco (ESAB) Roto-Ground, Lenco, Sumner, and others.

ROTOCON brushless rotating grounds are widely used in rotary welding cells, rotary plating processes, and other high current applications which require a rotary ground.  Although referred to as a rotary ground, these can be used for both power (positive) and return (ground) circuits with no impact on performance or lifespan.

ROTOCON brushless electrical rotary grounds are also offered in non-mercury, RoHS versions. Additionally, Meridian Laboratory can design and deliver Custom ROTOCON Rotary Grounds to meet your exact specifications in a cost and time efficient manner.
