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.

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

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.
