Gold contact capsule slip rings provide, thanks to a precious gold to gold contact, optimum contact resistance, mechanical and electrical properties for harsh environment and excellent resistance to corrosion. Since brushes are closely spaced into V-grooved rings, gold contact technology offer very good compactness. The operation is extremely reliable and maintenance-free up to several hundred million rotations without components change or lubrication.
They can be combined with other types of rotary joints such as FORJ, Hydraulic or Hyper Frequency.
