Features include:

  • High resistance to vibration and shock
  • Temperatures up to 200 degrees Celsius
  • High resistance to tropical conditions
  • Circumferential speeds of up to 40m/s
  • Max. diameter of the slip rings 350mm
  • Max. total length 420mm

Injection-moulded slip ring collectors

Features include:

  • Max. outside diameter 100mm
  • Plastic with 30% glass fibre reinforcement
  • Steady-state temperatures of max. 120°C
