SCHLEIFRING covers more than 90% of the worldwide requirement for sophisticated electrical rotary joints and slip ring systems for CT scanners.
These rotary joints with free inner diameters of up to 1,800 mm facilitate the supply of power for the X-ray tube (up to 700V and 250A), the transmission of all BUS systems as well as the non-contacting transmission of digital detector/ scanning data of at present up to 10 GBit/s.

Classic example:
