①Operation of actuator
When an actuator, such as a cylinder, is to be driven using a valve, take
a ro riate measures to revent otential danger caused by actuator
o eration
②
②②
②Intermediate stopping
When a 3 osition closed center valve is used to sto a cylinder at
intermediate osition, accurate sto ing of the iston in a
redetermined osition is not ossible due to the com ressibility of air.
Furthermore, since valves and cylinders are not guaranteed for zero air
leakage, it may not be ossible to hold sto ed osition for an
extended length of time. Contact SMC if it is necessary to hold a
sto ed osition for an extended time.
③
③③
③Effect of back pressure when using a manifold.
Use caution when valves are used on a manifold, an actuator
malfunction due to back- ressure may occur. S ecial caution must be
taken when using 3 osition exhaust center valve or when driving a
single acting cylinder. To revent a malfunction, im lement counter
measures such as using a single EXH s acer assembly or an individual
exhaust manifold.
④
④④
④Holding of pressure(including vacuum)
Holding of pressure(including vacuum)Holding of pressure(including vacuum)
Holding of pressure(including vacuum)
Since valves are subject to air leakage, they cannot be used for
a lications such as holding ressure (including vacuum) in a ressure
vessel.
⑤
⑤⑤
⑤Cannot be used as an emergency shut off valve, etc.
The valves resented in this o eration manual are not designed for
safety a lications such as an emergency shut off valve. If the valves
are used in this ty e of system, other reliable safety assurance
measures should also be ado ted.
⑥
⑥⑥
⑥Maintenance space
The installation should allow sufficient s ace for maintenance activities
(removal of valve, etc.).
⑦
⑦⑦
⑦Release of residual pressure
Provide a residual ressure release function for maintenance ur ose.
Es ecially in case of 3 osition closed center valve or erfect valve,
ensure the release of residual ressure between valve and cylinder.
⑧
⑧⑧
⑧acuum applications
When a valve is used for vacuum switching, etc. take measures against
the suction of external dust or other contaminants from vacuum ads
and exhaust orts, etc. Moreover, an external ilot ty e valve should be
used in this case. Contact SMC in case of an internal ilot ty e or air
o erated valve, etc.
⑨
⑨⑨
⑨About using the double solenoid type
When using the double solenoid ty e for the first time, actuators may
travel in an unex ected direction de ending on the switching osition
of a valve. Im lement countermeasures not to occur any danger by the
actuator’s o eration.
⑩
⑩⑩
⑩About ventilation
When it is used inside a sealed control anel, etc. rovide ventilation to
revent a ressure increase caused by exhausted air inside the control
anel or tem erature rise caused by the heat generated by valve.

① Momentary energizatuon
If a double solenoid valve will be o erated with momentary
energization, it should be energized for at least 0.1 second.
However, de ending on the secondary load conditions, it should
be energized until the cylinder reaches the stroke end osition,
as there is a ossibility of malfunction otherwise.
②
②②
② Leakage voltage
When using a resistor in arallel the switching element or using a
C-R element (surge voltage su ressor) for rotection of the
switching element, note that leakage voltage will increase due to
leakage current flowing through the resistor or C-R element. Limit
the amount of residual leakage voltage to the following values.
①
①①
①Confirm the specifications
The roducts resented in this o eration manual are
designed only for use in com ressed air systems (including
vacuum). Do not o erate at ressures or tem eratures, etc.
beyond the range of s ecifications, as this can cause
damage or malfunction. (Refer to s ecifications.) Contact
SMC when using a fluid other than com ressed air (including
vacuum).
②
②②
②Long period of continuous energization
・Continuous energization of the valve for extended eriods of
time may have an adverse effect on the solenoid valve
erformance and the eri heral equi ment due to tem erature
rises caused by the heat generation of the coil. Please consult
SMC if valves will be continuously energized for extended
eriods of time or the energized eriod er day will be longer
than the de-energized eriod. It is also ossible to shorten the
energization eriod by using valves of the N.O. (normally o en)
ty e.
・When solenoid valves are mounted in a control, em loy
measures to radiate excess heat, so that tem eratures remain
within the valve s ecification range. Use s ecial caution when
three or more stations sequentially aligned on the manifold are
continuously energized since this will cause a drastic
tem erature rise. (As for AC s ecifications, since the a licable
merchandises are ready to rovide se arately, lease contact
SMC.)
DC coil: Should be 3% or less of the rated voltage
AC coil: should be 8% or less of the rated voltage

Solenoid valve drive for AC with solid state output
(SSR, TRIAC output, etc.)
1)Voltage leakage
When using a snubber circuit (C-R element) for surge rotection
of the out ut element, very small electric current will still continue to
flow in s ite of the OFF state. This results in the valve not returning.
In the cases when exceeding the tolerance as shown above, take
measures to install a bleeder resistor.
2) Minimum allowable load (Min. load current)
When the consum tion current of a valve is equal or less than the
out ut element’s the minimum allowable load volume or the margin
is small, the out ut element may not be switched normally. Please
confirm SMC.

If a surge rotection circuit contains non-ordinary diodes such as
Zener diodes or Varistor, a residual voltage that is in ro ortion to
the rotective elements and the rated voltage will remain.
Therefore, give consideration to surge voltage rotection of the
controller. In the case of diodes, the residual voltage is
a roximately 1 V.

for air blow
When using a solenoid valve for air blow, use an external ilot ty e.
Take note that when internal ilots and external ilots are used on
the same manifold, the ressure dro caused by the air blowing can
have an effect on the internal ilot ty e valves. Moreover, when
com ressed air within the ressure range of the established
s ecifications is su lied to the external ilot ort, and a double
solenoid valve is used for air blowing, the solenoids should normally
be energized when air is being blown.

1.Attaching and Detaching Connectors
･To attach a connector, hold the lever and connector unit between
your fingers and insert straight onto the ins of the solenoid valve
so that the lever’s awl is ushed into the groove and locks.
･To detach a connector, remove the awl from the groove by ushing
the lever downward with your thumb, and ull the connector straight
out.
･Connect the standard ty e in accordance with the +,- olarity
indication.(The non- olar ty e can be used with the connections
made either way.)
･Since voltage s ecificaitons other than standard 24V and 12 VDC
do not have diodes for olarity rotection, be careful not to make
errors in the olarity.
･When wiring is done at the factory, ositive (+) is red and negative
(

) is black.
2.Crimping connection of lead wire and socket
Stri 3.2 to 3.7mm of the lead wire end, insert each stri ed wire into
a socket and clim contact it using s ecial crim ing tool. Be careful
that the outer insulation of the lead wires does not interfere with the
socket contact art.(Contact SMC for a s ecial crim ing tool.)
3.Connection/Disconnection of Socket with lead Wire
1)Connection
Insert a socket into the square hole (Indicated as +,-) of connector,
ush the lead wire in and it by hanging the hook of socket to the
seat of connector.(Pushing-in can o en the hook and lock it
automatically.) Then confirm the lock by lightly ulling on the lead
wire.
2)Disconnection
For ulling-out the socket from the connector, ull out the lead wire by

manifold block on the side indicated by an arrow on the to of the
solenoid valve. Therefore, arrange the i ing on the side indicated by
the arrow.
Although the “T”side will not be used, lugs will not be necessary since
it is sealed with the valve
Caution
One-touch Fittings
The itch determined for each of the series SY i ing orts(P, A, B,
etc.) is based on the assum tion that series KJ one-touch fittings will be
used. For this reason, other i e fittings may interfere with each other
de ending on their ty e and size. Dimensions should be confirmed in a
i e fitting catalog before they are you used.
Caution
Plug-in
Plug-in ty e solenoid valves consist of a non- olar solenoid valve and a
lug-in socket. When ordering them se arately, refer to the following art
numbers. .
Note) using a valve other then a non- olar ty e may cause trouble
Manifold Mounting
DIN rail for Series SY9000
The DIN rail used with Series SY9000 is stronger than that used with
Series SY3000 and SY5000. Use this exclusive DIN rail with Series
SY9000. Furthermore, if using a DIN rail other than that su lied by
SMC, refer to the manifold mounting section below, and mount using
the same method as rescribed for side facing and rear facing,
regardless of the mounting orientation.

Specific Product Precautions 6
Be sure to read before handing.
For Ty e 23, 43, 45 and 45□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 sim ly 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 s ecified
number of locations, war ing or twisting may occur in the DIN rail and
manifold, causing trouble such as air leakage.

･Tubing attachment/detachment for One-touch fittings
1)Attaching of tubing
1.Take a tubing having no flaws on its eri hery and cut it off at a right
angle. When cutting the tubing, use tubing cutters TK-1, 2 or 3. Do
not use inchers, ni ers or scissors, etc., If cutting is done with
tools other than tubing cutters,the tubing may be cut diagonally or
become flattened, etc., making a secure installation im ossible, and
causing roblems such as the tubing ulling out after installation or
air leakage. Allow some extra length in the tubing.
2.Gras the tubing and ush it in slowly, inserting it securely all the way
into the fitting.
3.After inserting the tubing, ull on it lightly to confirm that it will not
come out.If it is not installed securly all the way into the fitting, this
can cause roblems such as air leakage or the tubing ulling out.
2)Detaching of tubing
1.Push in the release button sufficiently, ushing its collar equally
around the circumference.
2.Pull out the tubing while holding down the release button so that it
does not come out.If the release button is not ressed down
sufficiently, there will be increased bite on the tubing and it will
become more difficult to ull it out.
3.When the removed tubing is to be used again, cut off the ortion
which has been chewed before reusing it. If the chewed ortion of
the tubing is used as is, this can cause trouble such as air leakage or
difficulty in removing the tubing.
・The itch determined for each of the seies SY i ing orts(A, B, etc.)
is based on the assum tion that serise KJ one-touch fittings will be
used. For this reason, other i e fittings may interfere with each
other de ending on their ty e and size. Dimensions should be
confirmed in a i e fitting cataloge before they are used.
One-touch Fittings M8 Connector
1.M8 connector ty es have an IP65(enclosure) rating, offering
rotection from dust and water. However lease note: these
roducts are not intended for use in water.
Select a SMC connector cable(V100-49-1-□) or a FA sensor ty e
connector, with M8 threaded 3 in s ecifications conforming to
Ni on Electric Control Equi ment Association Standard,
NECA4202 (IEC60947-5-2). Make sure the connector O.D. is
10.5mm or less when used with the Series SY3000 manifold . If
more than 10.5mm, it can not be mounted due to the size.
2.Do not use a tool to mount the connector, as this may cause
damage.Only tighten by hand.(0.4 to 0.6N･m)
Caution
Other Tubing Brands
When using other than SMC brand tubing, confirm that the
following specifications are satisfied with respect to the outside
diameter tolerance of the tubing.
Caution
1) Nylon tubing within±0.1mm
2) Soft nylon tubing within±0.1mm
3) Polyurethane tubing within±0.15mm,
Within –0.2mm.
Do not use tubing which do not meet these outside diameter tolerances.
It may not be ossible to connect them, or they may cause other trouble,
such as air leakage or the tubing ulling out after connection.
Caution
Caution
Failure to meet IP65 erformance may result if using alternative
connectors than those shown above, or when insufficiently tightened.
Note)Connector cable should be mounted in the correct
direction.Make sure that the arrow symbol on the connector is facing
the triangle symbol on the valve when using SMC connector cable
(V100-49-1-□).
Be careful not to sqeeze it in the wrong direction, as roblems such
as in damage may occur.
