UHV Magnetically Coupled

Magnetically coupled feedthroughs offer exceptional linear/rotary motion for short to medium stroke sample introduction and transfer of light loads. The standard magnetic driver package provides more than 50 ounce-inches (1.059 Nm) of torque and four pounds of linear force. The inside traveler has no magnets, but it is made of magnetically permeable material. The coaxial design features a .75 inch (19.05mm) linear support tube with rotary bearing in the tip to guide the .25 inch (6.35mm) rotary prove. In addition to rotary motion, the design includes a linear driver, for additional axial force and tactile feedback.

UHV Magnetically Coupled Features

  • 304 stainless steel materials, Teflon insert
  • Additional configurations for light-touch magnet or soft-touch magnet available, depending on the feedthrough
  • Horizontal operating orientation
  • Linear Motion up to 48”, Rotary 360° continuous
  • Maximum bakeout of 200°C with drive removed
