Auto Switch Rail Position
When free-mounting cylinders equipped with D-A9
or D-F9 type auto switches are used, be sure to
provide an extra clearance in addition to what is
suggested in the table at right. If the distance between
two cylinders is less than the noted value, auto
switches may malfunction. When for some reason you
cannot avoid installing cylinders closer than the
required clearance, install a steel plate or magnetic
shield plate (MU-SO25) on the side of the cylinder
facing the auto switches to shield them. (Contact SMC
for details.) Auto switches may malfunction if a
shielding plate is not used.
