1. Do not drop, bump, or apply excessive
impacts (980 m/s
2
) while handling. Although
the body of the sensor may not be damaged,
the internal parts of the sensor could be
damaged and lead to a malfunction.
2. The tensile strength of the cord is 35 N.
Applying a greater pulling force on it can
cause a malfunction. When handling, hold
the body of the sensor––do not dangle it
from the cord.
3. Do not exceed the screw-in torque of 7 to 9
N
⋅
m when installing piping. Exceeding this
value may cause malfunctioning of the
sensor.
4. Do not use pressure sensors with corrosive
and/or flammable gases or liquids.
5. Allow a sufficient margin of tube length in
piping in order to prevent application of
torsional, tensile or moment load to the
tubes and fittings.
6. When a brand of tubing other than SMC is
used, make sure that the tolerance of the
tube’s O.D. satisfies the following
specifications.
1) Nylon tubing:
±
0.1 mm or less
2) Soft nylon tubing:
±
0.1 mm or less
3) Polyurethane tubing: +0.15 mm or less, –0.2 mm or less
7. The applicable fluid is air. Please consult
with SMC if the switch is to be used with
other types of fluids.
Warning
Handling
1. Incorrect wiring can damage the switch and
cause a malfunction or erroneous switch
output. Connections should be done while
the power is turned off.
2. Do not attempt to insert or pull the pressure
sensor or its connector when the power is
on. A switch output malfunction may occur.
3. Wire separately from power lines and high
voltage lines, avoiding wiring in the same
conduit with these lines. Malfunctions may
occur due to noise from these other lines.
4. If a commercial switching regulator is used,
make sure that the F.G. terminal is
grounded.
Connection
Warning
1. Our pressure switches are CE marked;
however, they are not equipped with surge
protection against lightning. Lightning surge
countermeasures should be applied directly
to system components as necessary.
2. Our pressure switches do not have an
explosion proof rating. Never use in the
presence of an explosive gas as this may
cause a serious explosion.
3. Do not use in an environment where static
electricity can cause problems, otherwise
system failure or malfunction may result.
Operating Environment
Warning
2. Mounting with bracket
Mount a bracket to the body using two M3 x 5L mounting
screws and install on piping with hexagon socket head cap
screws. The switch can be installed horizontally depending on
the installation location.
Caution
Mounting
Tightening torque for bracket mounting
