Rotary Joints

HRM-RPA Series

sFeatures

1.Long Life

These non-contact rotary joints have a long life of

2.High Performance

High frequency characteristics feature extremely

low loss and a high degree of matching.

V.S.W.R. 1.25 or less (HRM-RPA-JJ-3 1.5~1.7GHz)

3.Low Torque Rotation

Rotation at low torque permits high speed rotation.
