Note 1) When used under conditions which may cause condensation on the exterior of the product,
select Grommet / Molded.
Note 2) When used with deionized water, select “L” (Stainless steel, FKM) for the material type.
Note 3) Since the AC coil specification includes a rectifier element, there is no difference in power con-
sumption between inrush and holding.
In the case of 110/220 VAC, the VDW10 is 3 W and the VDW20/30 is 3.5 W.
Note 4) Vibration resistance ····· No malfunction when tested with one sweep of 5 to 200 Hz in the axial
direction and at a right angle to the armature, in both energized and
deenergized states.
Impact resistance ········ No malfunction when tested with a drop tester in the axial direction and
at a right angle to the armature, one time each in energized and
deenergized states.
Note 5) Since electrical connections are exposed, there is no water resistance.
Characteristic Specifications
Note 1) The maximum operating pressure differential changes depending on the flow direction of the
fluid. Refer to page 264 for details.
Note 2) For low vacuum specifications, the operating pressure range is 1 Torr (1.33 x 10
2
Pa) to 1.0
MPa.
Please consult with SMC if using below 1 Torr (1.33 x 10
2
Pa).
