[Single solenoid]
í When using a double solenoid valve (Dual body type: SY 245-
Manifold valve
SS5Y -45 (N)„
Plug-in type solenoid valves consist of a non-polar solenoid valve
and a plug-in socket. When ordering them separately, refer to the
following part numbers.
Note) Using a valve other than a non-polar type may cause trouble.

„FU) on the plug-in style manifold (SS5Y -45(N)„), two
manifold stations are required per valve.
Output to A/B ports will be made through the manifold block on
the side indicated by an arrow on the top of the solenoid valve.
Therefore, arrange the piping on the side indicated by the
arrow.
Although the “T” side will not be used, plugs will not be
necessary since it is sealed with the valve.
(However, insert a plug into the A/B ports if dust intrusion is
possible. Refer to page 275.)

For Type 23, 43, 45, 45„ and 60 DIN rail mounting, when
attaching a manifold to a mounting surface, etc., with bolts, if the
entire bottom surface of the DIN rail contacts the mounting
surface in a horizontal mounting, it can be used by simply
securing both ends of the DIN rail. However, for any other
mounting method or for side facing and rear facing, etc., secure
the DIN rail with bolts at uniform intervals using the following as a
guide: 2 to 5 stations at 2 locations, 6 to 10 stations at 3
locations, 11 to 15 stations at 4 locations, and 16 to 20 stations at
5 locations. In addition, even in the case of a horizontal mounting,
if the mounting surface is subject to vibration, etc., take the same
measures indicated above. If secured at fewer than the specified
number of locations, warping or twisting may occur in the DIN rail
and manifold, causing trouble such as air leakage.
Also, when using mounting screws for the DIN rail on the bottom
side (L3 dimension in the dimension table) of the manifold valve
body, the height of the screw head has to be as follows.
Type 23, 43 (SY9000): 8 mm or less
Type 45 (SY3000, 5000): 5.8 mm or less
For type 60:
SY3000: 4.7 mm or less
SY5000: 5.8 mm or less
SY7000: 8 mm or less
The DIN rail used with Series SY7000 and SY9000 is stronger
than that used with Series SY3000 and SY5000. Use this
exclusive DIN rail with Series SY7000 and SY9000. Furthermore,
if using a DIN rail other than that supplied by SMC, refer to the
manifold mounting section below, and mount using the same
method as prescribed for side facing and rear facing, regardless
of the mounting orientation.
