Compound Slip Ring (photoelectric, liquid, gas)

Description of our compound slip ring:
  • The photoelectric and liquid (gas) compound slip ring is used between the rotor and stator for transmission of various signals and liquid (gas) medium simultaneously.
  • Our compound slip ring can adopt radial direction integration with high concentricity and compact size.
  • Our compound slip ring can adopt axial direction integration with easy and convenient disassembly and maintenance.
  • High speed photo signal transmission and high bandwidth, where WDM technology can be adopted.
  • Our compound slip ring ensures there is no leakage of signal transmission and no electromagnetic interference. It is in a good position to realize long distance and multi-channel bi-directional transmission.
  • It adopts non-contact transmission of the photo signals, without friction wearing so to realize long working life.
  • The photo signal transmission does not produce any electric spark and it can be used in hazardous environment such as combustible environment or explosive environment.
  • The liquid (gas) channel uses special sealing according to different transmission medium, working pressure and working environment to ensure long working life.
  • It is designed to avoid crossed contamination when there are different mediums transmitted in the liquid (gas) channel.
Features of our compound slip ring:
  • Compact structure with small size, easy for installation.
  • Photo signal transmission channel allows bi-directional transmission with low insertion loss and strong anti-interference capability against Electro Magnetic Interference (EMI).
  • The liquid (gas) channels are designed to avoid leakage with high reliability.
  • It is able to integrate two or more transmission mediums.
Typical Applications of our compound slip ring:
  • Radar system.
  • Ships and vessels.
  • Heavy Industry.
Customized Options:
  • Outline dimensions.
  • Installation size and installation mode.
  • Materials of housing.
  • Surface treatment.
  • Electric connection (wiring and connector) and location.
  • Experiment projects.
