Mercotac Model 330

They have low internal resistance and usually pin connections, but they can also be produced with optional wires if desired. Since they provide transmission through mercury, their working principles are different from slip rings with other transmission technologies. In other words, Mercotac Model 330 or similar products can work for a long time. This will reduce your costs.

During rotation, the liquid protects the electrical connection between the contacts without any wear. Thus, they are long-lived enough to make an average of 2 billion revolutions. The quality of the transmission signal always remains the same at a high level. They provide a high level of transmission of even very sensitive signals at high rotation speeds.

These types of slip rings use mercury metal as the conductive medium. During the spinning process, the mercury creates a connection between the stationary part and the rotating structure. This provides a high quality transmission connection with low sag resistance and less noise. Mercotac Model 330 is beautiful because it is a small and powerful product.
