ROTOCON MC Series 1-Pole High Current Slipring (Rotary Ground Clamp)
Meridian Laboratory’s full lineup of single contact, high current rotary ground clamps provide a consistent, maintenance-free contact unaffected by RPM or total number of revolutions. 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 single contact, high current ROTOCON MC & MCT Series rotary grounds are built with environmentally sealed and corrosion proof housings to ensure a long service life without maintenance.
