Rotation movement takes place at nearly every step of the process from bottle conveying to label placing. Sometimes, active components are embedded on a rotating plate and linked to the machine computer. Slip ring can perform this link while offering continuous rotation capabilities. Continuous rotation increase machine performance and reliability while easing the machine design. Slip rings can transfer all signal that can be met in such machines, motor power and control, sensors, field buses, etc. In some cases, integrating the motor manufacturer's proprietary cable such as Sercos III or Powerlink directly in the slip ring can make the solution more robust against electromagnetic perturbations.
