How to Order
∗ You do not need to specify "N" (i.e., without lead wire) for D-A3, D-A44, D-G39, and D-K39.
This is the only standard specification automatically available for these models.
∗ D-A9V, M9V, M9WV, and M9A(V) models cannot be mounted on ø25 to ø40.
∗ Lead wire length symbols: 0.5 m ······ Nil (Example) M9NW
1 m ······ M (Example) M9NWM
3 m ······ L (Example) M9NWL
5 m ······ Z (Example) M9NWZ
None ······ N (Example) H7CN
∗ Solid state auto switches marked "" are produced upon receipt of order.
∗ Since there are applicable auto switches other than listed, refer to page 310 for details.
∗ For details about auto switches with pre-wired connector, refer to pages 474 and 475.
∗D-A9, M9, and M9W type auto switches are shipped with the hydraulic cylinder (but not assembled). (However, they are auto switch mounting brackets are shipped with the
mounting brackets mounted already).
∗1 Water resistant type auto switches can be mounted on the above models, but in such case SMC cannot guarantee water resistance. ···(Applicable to ø20 only.)
Consult with SMC regarding water resistant types with the above model numbers.
∗2 1 m type lead wire is only applicable to D-A93.
