Installation
The relationship between the dimensions and positioning between the moving coil’s
coil winding section and magnetic ways’s magnets is shown here. Maintain the fol-
lowing air gaps when installing. Make sure that the moving coil and magnetic way do
not interfere with each other during the stroke.
2.
Move the moving coil back and forth several times over the magnetic
way from end to end, making sure that the moving coil and magnetic
way are not touching each other and that no foreign objects such as
magnetic particles are present.
