∗ Solid state auto switches marked with “ ” are produced upon receipt of order.
∗ Do not indicate suffix “N” for no lead wire on the D-A3lA/A44A/G39A/K39A types.
∗ The D-G39A/K39A cannot be mounted on the bore size ø20.

∗ Since there are other applicable auto switches than listed above, refer to Best Pneumatics.
∗ For details about auto switches with pre-wired connector, refer to pages 1328 and 1329 in Best Pneumatics No. 2.
∗ The D-A9
l/M9l/M9lW type auto switches are shipped together, (but not assembled). (However, auto switch mounting brackets are assembled when
being shipped.)
∗ Water resistant type auto switch can be mounted to the models with the above mentioned part numbers, but this does not guarantee the water resistance
of the cylinder. A water resistant type cylinder is recommended for use in an environment which requires water resistance.
∗ For other applicable auto switches, please contact SMC.

∗ Other intermediate strokes can be manufactured upon receipt of order.
Manufacture of intermediate strokes in 1 mm intervals is possible. (Spacers are not used.)
∗ Operate the cylinder within the allowable kinetic energy. Refer to page 4 for details.
• Auto switch proper mounting position
(detection at stroke end) and its mounting
height
• Minimum stroke for auto switch mounting
• Operating range
• Auto switch mounting brackets/Part no.
Refer to pages 13 to 16 for cylinders with
auto switches.
1 double clevis, 3 liners,
1 clevis pin, 2 retaining rings
1 trunnion, 1 trunnion nut
Warning
1. Operate the cylinder within the
specified cylinder speed, kinetic
energy and lateral load at the rod
end.
2. The allowable kinetic energy is dif-
ferent between the cylinders with
male rod end and with female rod
end due to the different thread
sizes. Refer to page 4.
3. When female rod end is used, use
a washer, etc. to prevent the con-
tact part at the rod end from being
deformed depending on the mate-
rial of the work piece.
Caution
1. Use a thin wrench when tightening
the piston rod.
