In situations where there are no requirements to pass services or devices through from the atmostpheric side into the vacuum system, magnetically-coupled linear drives offer a viable alternative to traditional bellows-sealed devices such as linear shifts.

Magnetically-coupled linear shifts offer exceptional reliability for applications with a high duty cycle such as operating shutters on production deposition systems. They are also preferred for applications where an unexpected failure would cause significant disruption such as beamline diagnostics.

Key Features

  • Exceptional reliability
  • Axial coupling up to 90N
  • Speeds up to 1,000mm/s
  • Fail-safe operation maintains vacuum integrity
  • UHV compatible
