Electrical Rotating Connectors

 

AOOD rotating electrical connectors (also called mercury slip rings) use a unique design principle unlike the sliding, brush contact slip rings, the connection is made through a pool of liquid metal molecularly bonded to the contact, which provides a low-resistance and stable connection. During rotation the fluid maintains the electrical connection between the contacts without any wear. Just because of the no wear contacting, it can provide superior performance than electrical slip rings in some special applications, such as require up to thousands of amps high current transfer welding machines or require extremely low electrical noise applications or high speed applications.

Features

■ Single pole current can up to 7500A

■ Speeds up to 3600RPM

■ Through bore type optional

■ Suitable for high speed or low noise applications

Typical Applications

■ Welding machines

■ Cutting machines

■ Textile machines

■ Strain gages

■ Sanitary towel machines
