Three Conductor Brushless Slip Rings

Mercotac® provides reliable slip rings for three-wire applications in robotics, cable reels, and various equipment. The model 330 and 335 are suitable for higher current applications, while the models 305 and 331 offer a cost-effective solution for lower current electronic uses. Mercotac® Brushless Slip Rings employ a superior liquid metal conduction path, providing a constant, low-resistance connection throughout the slip ring's life. In contrast, brush-type slip rings are prone to wear, high resistance, and electrical noise. By designing systems to use Mercotac Brushless Slip Rings, you can ensure reliable, long-lasting connections free from these issues.
