Precision Rotary Feedthroughs FPRM Series Precision Rotary Feedthroughs, FPRM Series Description FPRM-275-28 shown with optional /MS/W Precision rotary feedthroughs are commonly used to define a polar axis for a sample or probe. They provide 360° continuous rotation and are mounted on top of XYZ manipulators and other stages to provide polar axis freedom. They are also used separately where precision angular orientation is needed. These feedthroughs are available with custom probe lengths for your specific application. Field-mountable probe extensions are also available. All are available with optional anti-backlash stepping motor drive.
