Mercury slip ring A series (mercury rotary joint)

  • Anti-interference, low cost
  • Contact resistance is less than the 1mΩ
  • No maintenance, better reliability than traditional slip ring
  • Suitable for signal and power transmitting of any rotating devices
  • Mercury slip ring is used with special sealing materials,insulation and conductive technology production
  • Housing material is made of aluminum alloy or stainless steel
  • Applied for any rotating objects of signal transmitting such as:tiny voltage¤t,EMF,thermocouple,strain gauge,audio and video signals, high frequency,computer signal and electric power connections;
