Ferromagnetic Feedthrough

 

Magnetic feedthrough is the ideal way to transfer rotational motion from atmosphere to vacuum or overpressure environment. Benefits are friction-less motion, high torque transmission, high speed (>10,000 rpm) capability, low drag torque, smooth motion and no particle generation withstand process operation without degrading.

Common use of ferro feedthrough are:
1) Cost effective replacement of O-ring rotary feedthrough
2) Sample handling, position and Robotics  
3) Substrate rotation in vacuum chamber
4) Agitate fluid under vacuum
5) Damper for vibration-free application
6) Hermetic seal for clean environment
