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.
Rie-Tech develops and manufactures slip-ring units (electrical rotary joints) according to the electrical and mechanical specifications and requirements of the respective customer. Through this a high performance and continuous, safe and trouble-free operation can be achieved.
Wherever possible the slip ring assembly is delivered as a complete and sealed-housed assembly. This eliminates the danger of contamination 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 Rie-Tech slip rings or electrical rotary joints enables new solutions for machine designers towards an optimised problem solution.
With the consequential use of the gold-gold technology a safe transmission of electricity to a rotating shaft can be guaranteed. This opens up solutions in many areas of the machine building industry such as:
