FAQs

Common Custom Rotary Ground Questions

What is the minimum quantity required for a custom ROTOCON?

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!

What is the expected lifespan of a ROTOCON rotary ground?

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.

Do you offer a rotary ground with an integrated rotary gas union?

Yes, Meridian Laboratory offers a standard model ERGT-800-1PRU, offering the functionality of being both a rotating electrical ground and a gas/air union combined into one solution. We also offer custom rotary grounds and rotary unions based on the specific needs of your application. Please visit our Rotary Union Combination page or contact us to learn more.

What is the average lead time?

Lead times vary based on the specific model and quantities being requested. Some of our standard ROTOCON models are in-stock, or have the ability to be ready in a matter of weeks. For basic customizations, we generally estimate a lead time of 4-8 weeks. The delivery time for very specific and in-depth custom ROTOCON rotary electrical connectors largely depends on the scope of the project and specific details of the application. Please contact us for more information relative to your specific project and how we can support your needs.

Can a ROTOCON be used with high frequency signals or power?

Yes, certain ROTOCON rotary electrical connectors and rotary grounds are able to carry high frequency signals and power. Contact the Technical Sales Team to discuss detailed specifications.

Can a ROTOCON rotary ground be used as a rolling contact?

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.
