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 within±0.1mm
2) Soft nylon tubing within±0.1mm
3)Polyurethane tubing within±0.1mm
within±0.1mm
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
Triangle mark
Arrow mark
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.
