Connector Assembly with Cover
Caution
Connector assembly with dust proof protective cover
･Effective to prevention of short circuit failure due to the
entry of foreign matter into the connector.
･Chloroprene rubber for electrical use, which provides
outstanding weather resistance and electrical insulation,
is used for the cover material. However, do not allow
contact with cutting oil, etc.
･ Simple and unencumbered appearance by adopting
round-shaped cord.
One-touch fittings
Caution
･Tubing attachment/detachment for One-touch fittings
1) Attaching of tubing
1. Take a tubing having no flaws on its periphery and
cut it off at a right angle. When cutting the tubing,
use tubing cutters TK-1,2 or 3. Do not use pinchers,
nippers 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
problems such as the tubing pulling out after
installation or air leakage. Allow some extra length in
the tubing.
2. Grasp the tubing and push it in slowly, inserting it
securely all the way into the fitting.
3. After inserting the tubing, pull on it lightly to confirm
that it will not come out. If it is not installed securely
all the way into the fitting, this can cause problems
such as air leakage or the tubing pulling out.
2) Detaching of tubing
1.Push in the release button sufficiently, pushing 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 pressed down sufficiently, there will be
increased bite on the tubing and it will become more
difficult to pull it out.
3. When the removed tubing is to be used again, cut off
the portion which has been chewed before reusing it.
If the chewed portion of the tubing is used as is, this
can cause trouble such as air leakage or difficulty in
removing the tubing.

impossible, and causing
Other Tubing Brands
Caution
1. When using other than SMC brand tubing, confirm that
the following specifications are satisfied with respect to
the outside diameter tolerance of the tubing.
1) Nylon tubing
2) Soft nylon tubing
3)Polyurethane tubing
Do not use tubing which do not meet these outside
diameter tolerances. It may not be possible to connect
them, or they may cause other trouble, such as air
leakage or the tubing pulling out after connection.
M8 connector
Caution
1. M8 connector types have an IP65 (enclosure) rating,
offering protection from dust and water. However please
note: these products are not intended for use in water.
Select a SMC connector cable or a FA sensor type
connector, with M8 threaded 3 pin specifications
conforming to Nippon Electric Control Equipment
Association Standard,
Make sure the connector O.D. is 10.5mm or less when
used with the Series SYJ3000 manifold. If more than
10.5mm, it cannot 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 0.6 N･m)
Caution
Failure to meet IP65 performance may result using
alternative connectors than those shown above, or when
insufficiently tightened.
Connector cable mounting
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.
Be careful not to squeeze it in the wrong direction,
as problems such as pin damage may occur.
