Electric slip rings enable the transmission of power and data currents from a stationary component to a rotating one, therefore they are often also called „electric rotary joints.
Very often slip rings are used in rotary machines. These are used by fillers cappers and weighers of food, beverage, household products or pharmacuticals, but also for packaging building materials such as cement or similar. Many other machines, such as labelling systems, are also suitable for these applications.
Slip rings are increasingly important as rotary packaging machines and lines become more and more complex with regard to automation, process visualization, analogue or digital sensor data, status conditions and power currents as well as system networking.
