(2) Magnetic Way: SGLTM-50†††H
Note: 1. Two magnetic ways for both ends of coil assembly make one set. Spacers are mounted on magnetic ways
for safety during transportation. Do not remove the spacers until the coil assembly is mounted on a
machine.
2. The magnetic way may affect pacemakers. Keep a minimum distance of 200 mm (7.87 in) from the
magnetic way.
3. Two magnetic ways in a set can be connected to each other.
4. The dimensions marked with an  are the dimensions between the magnetic ways. Be sure to follow
exactly the dimensions specified in the figure above. Mount magnetic ways as shown in Assembly
Dimensions. The values with an
♣ are the dimensions at preshipment.
5. Use socket headed screws of strength class 10.9 minimum for magnetic way mounting screws. Do not use
stainless steel screws.
