Mercotac® Electrical
Swivel Connectors

Electrical Swivel Connectors by Mercotac® operate on a superior principle. They offer an extremely low resistance electrical connection because the electrical conduction path is a liquid metal which is molecularly bonded to the contacts. The Mercotac® connection is constant and unchanged for the life of the electrical swivel connector. Brush slip rings are usually composed of a rotating metal ring upon which a graphite or metal brush rubs and transfers the electrical signal or current. While brush slip rings are technically simple in operation, this rubbing interface is fraught with problems that include wear, high e lectrical resistance, oxidation, and resistance fluctuations which causes electrical noise.





Video Demonstrations of the Mercotac®
Electrical Swivel Connector

The model train is powered through the small Mercotac coaxial swivel connector in the center of the table.
Below, power is transmitted to the light inside the rotating roller while simultaneously the thermocouple temperature signal from inside passes out through the Mercotac connector to the LED readout. This models a typical heated roller application for packaging, printing, and laminating equipment.
An oscilloscope compares the signal noise after passing through the Mercotac connector with a traditional brush type slip ring shown below. Learn More
