• Products Info

AOOD rotating electrical connectors (also called mercury slip rings or liquid metal slip rings) 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. They are the best solutions for those have low electrical noise, high speed or super high current transfer requirements systems.

Features
• Very low electric noise
• Very low cost
• Very low contact resistance
• No maintenance and high reliability
• Single pole current can up to 7500A

Typical Application
• Welding machines
• Cutting machines
• Textile machines
• Strain gages
• sanitary towel machines

Model Selection

A slip ring is an electromechanical device which in combination with brushes that allows the transmission of power and electrical signals from a stationary to a rotating structure.
