ABSTRACT:
A magnetic feedthrough manipulator adapted to be sealed to a chamber for inserting a manipulator shaft capable of rotational and longitudinal movement. The shaft is axially coupled to a ferromagnetic armature having an even number of longitudinal surface splines freely movable within a nonmagnetic tubular housing and which is controlled by alternately polarized magnets in a frame that slides and rotates on the outer surface of the housing. Two or more manipulator shafts may be controlled independently by a like number of armatures in the same housing.
