ROTOCON ERG-800 Model Specifications

» RoHS / CE Compliant versions available» 100% maintenance-free and arc-free design for uninterruptible machine output and usage
» Five robust mounting options, to meet the most demanding applications» Frequently surpass 500 million revolutions without demonstrating a change in electrical resistance or performance

The high-current ERG Series provides the perfect ground to meet the most demanding applications, and is available as 100% RoHS / CE compliant upon request. The flexible design offers an abundance of exciting options and mounting variations. With the ERG 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.

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 500M (million) revolutions without demonstrating a change in electrical resistance or performance. Contrary to conventional brushed rotary grounds, Meridian Laboratory’s ERG 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 without maintenance, even in the most challenging manufacturing environments and chemical exposure.

ERG-800s are also available in RoHS / CE Compliant versions.
