MRD91 Magnetic Rotary Drive
The MRD91 is a manual or motorised magnetic rotary drive which uses high strength Sm2Co17 magnetic coupling to transfer rotational forces into the vacuum envelope. This is achieved without any dynamic seals or bellows making these devices exceptionally robust and no risk of a vacuum leak for the life of the drive. The MRD91 is fitted with Index scale and position lock. The graduated handwheel provides 1° angular resolution which can be improved with a stepper motor. The magnetic coupling ensures the devices are exceptionally robust and cannot be damaged with excessive torque. The drive is fully bakeable to 250°C with the motors removed.
