Mercury Slip Ring

Mercury slip ring enjoys the same performance just like other electrical sliprings, both of them are a device which could provide 360 degree rotations to transmit signal and power between stator side and rotor side of different industry equipments. No doubt, mercury slip ring just take advantage of mercury contact as a conductive media, which only could transfer current and signal via liquid metal under normal temperature status. This kind of slip ring has the main feature of strong stability, high precious signal and no noise. Meanwhile, compared with the traditional mechanical sliprings, this mercury rotary connector is smaller size, earlier installation and free maintenance, etc. Mercury slip rings provide the most scientific, economical and profitable rotary solution for various application industries.

Notices:

  • Not exceed the max temperature 60℃(140°F ), ambient temperature + self heating.
  • Vertical mounting and storage should keep the U P in the up direction.
  • Mounting into a shaft should keep no eccentricity.
  • Do not solder on the connector and terminal.
  • Connect the connector on the terminal only a few times, losing connection will cause heating when apply electrical power.
  • Vibration will cause service life shorter.
  • The rotary connector can be mounted by the body or plastic collar, but it can not carry mechanical loads. Another end should be connected floating hold by electric wire.
  • The uppers notice should be kept, otherwise, it will cause the rotary connector failure or shorten service life.
