New AC7257 Slip Ring Offers Solutions for Packaging Systems

17 November 2014

Moog Components Group, a division of Moog Inc., has announced the introduction of a new slip ring. The AC7257 through-bore model provides power and signal communications via the Siemens hybrid cable for the Sinamics S120M drive system with DRIVE-CLiQ®. Typical applications are packaging systems, machine tools and work centers.

A key advantage of the Moog AC7257 slip ring is its unique fiber brush technology for no maintenance operation and long life. The AC7257 operates with speeds up to 1000 rpm continuous. The unit is sealed for dust and light fluid splash, with IP65 and stainless steel housing available.

In addition, this slip ring has been tested and verified compatible with the Sinamics S120M decentralized servo system, logging over 100,000 rotations with no loss of information. The ring and the brush contacts can operate in excess of 100,000,000 rotations.

The new AC7257 model is based on Moog’s proven technology and broad array of slip ring models and rotary solutions. A slip ring can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power and data from a stationary to a rotating device. Through-bore design offers flexibility in mounting or routing fluid and air lines.
