Limited Angular Rotary Joints


  • Transfer from DC high power to RF and very high frequency MW signals
  • Very smooth rotation
  • Rotational freedom - up to more than +/-200°
  • Low torque
  • Long performance (several millions of cycles)
  • Low out-gazing for space or any vacuum application

Limited Angular Rotary joints are an interesting alternative to slip rings and wave guides when no continuous rotation is required. These devices are not based on sliding contacts and therefore assure a continuous power and signal transfer while minimizing losses and perturbations. Several types of designs are possible in order to fulfill all kinds of customers’ requirements:

  • Twist capsules
  • Cable wrap
  • Rolling sheets
  • Goose neck

All these configurations are proven and mastered by RUAG Space Nyon.
