ROTOCON MC Series

Innovative Maintenance-Free Rotary Ground Clamp

Tired of poor rotary ground consistency? Consistently having to grease and maintain a metal-on-metal rotary ground? Is fluctuating resistance causing variable consistency in your process, leading to scrapped product?  If you are experiencing any of these problems associated with traditional rotary grounds, a ROTOCON rotary ground is the solution.

Meridian Laboratory’s full lineup of single contact, high-current rotary ground clamps provides a consistent, maintenance-free, rotating electrical contact and connection unaffected by instantaneous RPM (for high speed applications) or total number of revolutions; ROTOCON rotary grounds oftentimes surpass 1B+ revolutions without demonstrating a change in electrical resistance or performance. Contrary to conventional brushed rotary grounds, Meridian Laboratory’s MC & MCT Series are arc-free, do not have internal friction, and do not require greasing or any type of maintenance. All high current ROTOCON MC & MCT Series rotary grounds are built environmentally sealed, and with 304SS corrosion proof housings to ensure a long service life without maintenance, even in the most challenging manufacturing environments and chemical exposure.

Suitable for all environments and applications including rotary welding, electro-plating, electro-polishing, cutting, and other high current rotating industrial applications, the ROTOCON MC & MCT Series is designed to withstand 100% duty cycles in continuous manufacturing and production processes, without interruption or downtime. The ROTOCON’s brush-free design eliminates all issues such as maintaining brush contact and conductivity, does not require application of conductive greases, and eliminates elevated contact resistance associated with conventional brushed rotary grounds. With the MC Series, you will achieve a more consistent ground, with zero fluctuations in resistivity, or elevated contact resistance over time and revolutions; this will lead to a better end product in rotational welding, plating, polishing, and other high current applications that require rotation.  ROTOCON rotary grounds can be used interchangeably on the positive or negative (ground) of an application without any difference in performance.

ROTOCON rotary grounds are available both in end of shaft (MC-Series) and through-bore (MCT-Series) configurations in a range of amperage levels.  For applications requiring high frequency AC and high current (for sputtering deposition, and other similar applications), Meridian Laboratory offers specialized versions to accommodate for temperature rise due to eddy currents and skin effect.
