Plug and Play Hybrid Rotary Joint Solution for Simple and Reliable Integration

Indexing table with hybrid joint

Indexing tables are widely used in the industry, especially in body and white processes in the automotive industry. Those applications, therefore, require a pneumatic and/or hydraulic distribution along with electrical power and field bus to allow control and command of the equipment between the industrial network and the rotating work stations. In order to achieve a continuous 360° rotation, both rotary unions andSlip ring are needed

PES has developed a plug-and-play solution to answer this need and make integration easy for those who use rotary tables. It is made up of a single-pass rotary union combined with a thru-bore slip ring that offers 24V power supply, field bus connection (Profinet, Ethernet, EtherCAT, etc.) and optionally 400V power supply. This hybrid rotary union assembly comes with the mechanical parts to allow easy mounting on the rotary table. The latter comes this way equipped with the rotary interfaces that can meet nearly all automation application needs.
