Magnetically coupled rotary feedthroughs utilise a failsafe design that cannot be damaged by ‘over-torque’, compared to the more vulnerable bellows-sealed devices.

The outer magnetic sleeve is engraved with a laser etched scale, incremented at 5° intervals. Magnetically coupled rotary feedthroughs provide practical and economical solutions for most applications requiring rotary motion in high or ultra-high vacuum environments, such as window baffles, sample parking stages, etc.
