Abstract
A line scanner assembly includes a cam with a cam surface, where the cam rotatable about a cam axis of rotation and includes a first ferromagnetic material. A mirror with a planar surface is configured to tilt about a mirror axis of rotation. A follower is attached to the mirror and has a second ferromagnetic material, where the first magnetic material and/or the second magnetic material includes a permanent magnet and where the follower maintains contact with the cam due to a magnetic attraction between the first ferromagnetic material and the second ferromagnetic material.
