RF Slip Ring (Medium/High Frequency Slip Ring)

Description of our RF slip ring:
  • Our RF slip rings simulate coaxial cable structure, mainly used for transmission of MHF (medium/high frequency) signals, UHF (ultra high frequency) signals as well as electric power current and low frequency signals.
  • The through hole can be realized at the axis center.
  • All parameters of MHF and UHF pass accurate analysis and calculation to ensure the optimal comprehensive performance result.
  • Advanced sealing structure is adopted between the MHF/UHF signal channels with excellent insulation and shielding capability.
  • Superposition of electrical path along the axial direction, adopting gold to gold multi-points contact between with least resistance, reliable and endurable for long working life.
  • Capable of adapting to various environment such as high temperature, low temperature, impacting, vibration, salt spray, damp heat, water saturation, and etc.
Features of our RF slip ring:
  • Compact structure with least space between channels.
  • With RF interface connection, convenient for installation.
  • With least insertion loss and phase variation and highest insulation.
  • Strong anti-interference signal transmission with least loss.
  • Strong environment adaptation capability.
  • Can be integrated with current, low frequency, optical fiber, liquid (gas) rotary joints
  • Maintenance-free during working life.
Typical Applications of our RF slip ring:
  • Radar System.
  • High Definition Video Transmission.
  • Satellite Antenna.
