Electric rotary culverts Mercotac

Mercotac rotary electrical connectors (brushless slip rings) transfer electrical signals to rotating machine components, enabling the transmission of power, measurement and high-frequency signals. They are smaller, more durable and generate less noise than traditional brush systems.

Advantages of Mercotac connectors over slip rings:

  • Nearly zero electrical noise due to unique design  
  • Very low rotary contact resistance (less than 1 mΩ)
  • No signal degradation over time 
  • Maintenance-free, unlike slip rings that require maintenance
  • Compactness and lower cost
  • Ability to transmit both power and measurement signals through a single connector
