Electrical Rotary Joints, Slip Ring Assembly, Rotary Connections


A Slip Ring, also known as Electrical Rotary Joint, is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.

The safe transmission of electrical currents in the range of mA to several 100s of Amps. (welding currents) requires the use of high-quality contacting materials such as Gold-Gold. To cover the various technical needs such as transmission of data, ie. Profibus, Ethernet, video signals, high current supply etc. the internal design and routing of leads as well as proper shielding and the use of the correct cables and connectors is important for a successful product.


Packam has partnered with an international company to manufacture slip-ring units according to the electrical and mechanical specifications and requirements of the respective customer. Our technicians are trained in Europe and our assembly / testing facilities are approved by our partners. This ensures a high and consistent quality of every unit manufactured.


Wherever possible the slip ring assembly is delivered as a complete and sealed-housed assembly. This eliminates the danger of any environmental influence and makes the slip-ring assembly maintenance free.


Electrical rotary joints are often combined with rotary joints for air and/or liquids such as hydraulic oil. The use of Packam slip rings enables new solutions for machine designers towards an optimized problem solution.


With the use of the Gold-Gold technology, a safe transmission of electricity to a rotating shaft can be guaranteed. Packam Slip Rings find application in:
