ROTOCON® MC2F-6000 Model Specifications

»  Provides consistent low and stable resistance for high current applications»  Robust industrial design provides reliable long lasting performance
»  Requires ZERO grease or routine maintenance»  Remains unaffected by RPM or total number of revolutions

The high-current MC Series by Meridian Laboratory provides the perfect ground for rotational welding, plating, polishing, and other high-current applications that require rotation. Designed to withstand 100% duty cycles in continuous manufacturing and production processes, without interruption or downtime.

Contrary to conventional brushed rotary grounds, Meridian Laboratory’s MC Series are arc-free, do not have internal friction, and do not require greasing or any type of maintenance. All ROTOCON rotary grounds are built environmentally sealed, and with 304SS corrosion proof housings to ensure a long service life, even in the most challenging manufacturing environments and chemical exposure.

For applications requiring a through-bore, the ROTOCON ERGT Series electrical rotary grounds are listed in the chart below.
