NON-MERCURY SLIP RINGS & ROTARY GROUNDS

TECHNICAL FEATURES

NON-MERCURY SLIP RINGS & ROTARY GROUNDS FOR SENSITIVE APPLICATIONS

Non-mercury rotary grounds & slip rings available
Same performance & benefits as all ROTOCON brushless rotary grounds & slip rings
Ongoing development to expand non-mercury series

Meridian Laboratory designs and manufactures high-performance brushless slip rings and rotating electrical solutions for applications and industries worldwide. In some cases, it may be necessary to use a slip ring or rotary ground that does not contain elemental mercury due to environmental or material sensitivity requirements.

For these applications, Meridian Laboratory offers non-mercury, brushless, wetted slip rings and rotating electrical connectors. Our non-mercury slip rings and rotary grounds deliver the same high performance and benefits as our mercury-based models – both of which significantly outperform conventional metal-on-metal, brushed slip rings. Click here for a full list of benefits.

While Meridian Laboratory’s complete lineup of ROTOCON slip rings is not yet entirely mercury-free, we are actively and continuously working toward that goal. Our ongoing development focuses on expanding our range of brushless, non-contact rotating electrical connectors that do not utilize elemental mercury. With each new product generation, we are increasing our variety of high-performance, mercury-free solutions for power and signal transmission.

Advantages

Why Choose ROTOCON Non-Mercury Slip Rings?

ENVIRONMENTALLY SEALED BRUSHLESS TECHNOLOGY MAINTENANCE FREE

ENVIRONMENTALLY SEALED SLIP RINGS DELIVER SAFE AND LONG-LASTING OPERATION

All ROTOCON® slip rings and rotary grounds are environmentally sealed and safe for use across a wide range of applications. Their sealed, maintenance-free design makes ROTOCON technology the ideal choice wherever reliability is critical. From clean rooms to washdown areas and dusty industrial settings, ROTOCONs deliver consistent, safe, and dependable power and signal transmission.

For applications with heightened material sensitivities, non-mercury ROTOCON® models are available, ensuring compatibility with even the most sensitive environmental requirements, without compromising performance.

Bullet Points:

ENVIRONMENTALLY SEALED DESIGN
UNAFFECTED BY LIQUIDS, DUST, AND OTHER FACTORS
ROBUST DESIGN FOR HARSH ENVIRONMENTS

BRUSHLESS SLIP RING TECHNOLOGY PROVIDES SUPERIOR PERFORMANCE

ROTOCON non-mercury slip rings and rotary grounds are brushless by design, functioning through a molecularly bonded, liquid metal film contact to transfer electrical power and signal. ROTOCON brushless slip ring technology introduces near-zero electrical resistance while stationary or during rotation – regardless of rotational speed or total number of revolutions.

Bullet Points:

NEAR-ZERO ELECTRICAL NOISE, STATIONARY OR ROTATING
HIGH-SPEED CAPABLE WITHOUT FLUCTUATION IN ELECTRICAL RESISTANCE
NO INTERNAL WEAR PARTS

ENCLOSED SLIP RINGS WITHOUT MAINTENANCE

Conventional brushed slip rings rely on metal-on-metal contact to transfer power between stationary and rotating components. ROTOCON non-mercury slip rings and rotary grounds do not have any internal wear parts, and therefore do not require any maintenance, adjustment, or replacement of parts during their lifetime of use.

Bullet Points:

NO METAL-ON-METAL CONTACT
100% MAINTENANCE-FREE
OUTLAST TRADITIONAL BRUSHED SLIP RINGS

FAQs

Answers to Common Questions

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.

Are ROTOCON slip rings UL / CE Rated?

For most instances, UL and CSA certifying a single ROTOCON slip ring model poses cost and time prohibitive limitations. While they can be certified, the process is often time-consuming and costly in low volumes. Once a device receives UL/CSA certification, any modifications or revisions require re-certification and potentially additional testing, adding further expenses, especially for low-quantity slip ring orders. In most cases, the final machine or end product incorporating the ROTOCON brushless slip ring is what requires UL or CSA certification, for which Meridian Laboratory can provide the necessary documentation and support to assist in that certification process.

Are any ROTOCON models produced overseas?

No. Every ROTOCON rotary electrical connector is designed, manufactured, and tested in the United States at our Middleton, Wisconsin facility.

Where is Meridian Laboratory located?

Meridian Laboratory, Inc. is headquartered in Middleton, Wisconsin (USA). Every ROTOCON brushless slip ring is designed, manufactured, tested, and distributed from our Middleton facility.

Applications & Uses

Common Uses for Non-Mercury Rotary Grounds & Slip Rings

Wastewater Treatment

ROTOCON brushless non-mercury rotary grounds deliver current to the rotating anodes, which utilize electrocoagulation to remove suspended solids, heavy metals, and biological contaminants in wastewater.

Plating Line Equipment

ROTOCON non-mercury rotary grounds deliver a stable, high-amperage current to electroplating baths, ensuring a uniform deposition of plating material on your end product.

PCB Material Manufacturing

Non-mercury rotary grounds are used in PCB material manufacturing to provide a grounding circuit for rollers that experience static build-up and require a safe discharge path.
