FAQs
Common Rotary Ground Questions
ROTOCON rotary grounds are built to provide reliable, uninterrupted electrical contact over an extended operational lifespan, frequently surpassing 500 million revolutions without requiring cleaning, conductive grease, or brush maintenance. Our designs emphasize long-term performance and dependability, using carefully selected materials and components to ensure a robust, maintenance-free solution.
For the best electrical contact and performance, we recommend lightly scuffing the face of the ROTOCON flange and the mating flange using Scotch-Brite or fine finish sandpaper such as 240 grit. After scuffing, clean both surfaces thoroughly with isopropyl alcohol to remove any residue. Ensure that your lug or mating surface makes direct contact with the flange, maximizing the surface contact area. Avoid the use of any washers, conductive greases, or other materials between the contact surfaces. Secure the connection firmly. Please contact us for our model specific mounting guide or to discuss your application.
Yes, a ROTOCON rotary ground can serve as a rolling electrical contact in applications that require a continuous, low-resistance ground path. However, it’s important to verify that your application’s mechanical and electrical requirements align with the capabilities of the specific ROTOCON model. We recommend reaching out to discuss your specifications so we can ensure the best fit for your needs.
Yes, ROTOCON rotary electrical connectors and rotary grounds are built with durable, industrial-grade materials, making them suitable for many challenging environments. Depending on the level of exposure to corrosive substances, a standard model may be sufficient for your application. Meridian Laboratory also offers upgrades to enhance ingress protection (IP rating) and chemical resistance. For extreme cases, Meridian Laboratory has the ability to deliver custom ROTOCONs to meet the challenging environmental requirements of your application. Contact us to discuss your project and find the best solution for your needs.
There is no minimum order requirement for a custom ROTOCON slip ring. In most cases, we can tailor our standard models to fit your specific needs without a minimum quantity requirement.
For more complex or highly specialized projects, we work closely with your R&D and engineering teams to efficiently develop prototype, pre-production, and final production models at each stage of your project. Whether you need a single unit or a full production run, we are committed to delivering the right solution for your application. Contact us to discuss your requirements!
While it is expected that a certain amount of cable weight is present on the ROTOCON rotary grounds, they are not intended to be a load-bearing device used to support the objects being grounded and rotated. For exact ratings and more information, please see the model specific datasheets or contact us with any questions relative to your application.
