Slip rings need continual maintenance to avoid degradation of the rotating electrical connection caused by normal wear and debris. Even precious metal slip rings limit rotational speed and increase electrical noise and resistance with wear. When you replace conventional slip rings with Mercotac's no-maintenance, brushless rotating electrical connectors, you will profit from the following SUPERIOR BENEFITS:

• Increased reliability
• Long life
• Extremely low electrical noise
• LESS THAN 1 milliohm resistance
• Low voltage Signals and/or High Power in one compact connector
• Sealed ball bearing construction
• Durable, compact and low cost
• No Maintenance Required
• In stock availability
• Made in U.S.A.

THE UNIQUE DESIGN OF A MERCOTAC^® CONNECTOR:
Mercotac^® rotating connectors use a unique design principle unlike the sliding, brush contact of a slip ring. The connection is made through a pool of liquid metal molecularly bonded to the contact, which provides a low-resistance, stable connection. During rotation the fluid maintains the electrical connection between the contacts without any wear.

The following are among the many reasons why Mercotac^® connectors are superior to slip rings. First, unlike a slip ring, Mercotac^® connectors produce near zero electrical noise due to their unique design. Second, resistance through the rotating contact is less than one milliohm, which is much lower than the resistance of a slip ring. Third, Mercotac^® connectors do not degrade the signal over time, which does happen with slip rings. Fourth, slip rings require maintenance and Mercotac^® connectors are maintenance free. Fifth, Mercotac^® connectors are more compact and cost far less than slip rings of equal capacity. Sixth, both current power and instrumentation signals can be sent through a single, compact Mercotac^® connector.
