Take the following corrective solutions when errors occur.
Load current of switch
output is more than 80 mA.
Pressure is applied during the
zero out operation as follows:
When the switch for positive
pressure is used: ±0.071 MPa
or more.
When the switch positive
pressure is used:
±7.1 kPa or more.
After displaying for 3 seconds,
it will return to the measuring
mode.
Supply pressure exceeds
the maximum regulating
pressure.
Supply pressure is below
the minimum regulating
pressure.
Shut off the power
supply. After eliminating
the output factor that
caused the excess
current, turn the power
supply back on.
Bring the pressure
back to atmospheric
pressure and try
using the zero out
function.
Reduce/Increase
supply pressure to
within the regulating
pressure range.
Shut off the power
supply. Turn the
power supply back
on.
If the power should
not come back on,
please contact SMC
for an inspection.

Specific Product Precautions 1
Be sure to read before handling. Refer to front matters 58 and 59 for Safety Instructions
and pages 687 to 691 for Pressure Switch Precautions.
1. Do not drop, bump, or apply excessive
impacts (980 m/s2) 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 toxic,
corrosive and/or flammable gases.
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
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
screw should be 0.5 to 0.7 N⋅m.
1. Mounting with panel mount adapter
To release push the
clips outward as shown
on the picture, and pull
back towards you.

• To connect the connector, insert it straight while
pinching the lever, and then push the lever into the jack
of the housing and lock it.
• To remove the connector, pull it straight out while
applying pressure with your thumb to the lever and
unhooking it from the jack.
• Do not attempt to insert or pull the connector when the
power is on. A switch output malfunction may occur.
• Cut the tube perpendicularly.
• Hold the tube and insert it into the One-touch fitting
carefully and securely all the way to the bottom.

Regulating Pressure Range and Rated Pressure Range
Set the pressure within the rated pressure range.
The regulating pressure range is the range of pressure that is possible in setting.
The rated pressure range is the range of pressure that satisfies the specifications (accuracy, linearity, etc.) on the sensor.
Although it is possible to set a value outside the rated pressure range, the specifications will not be guaranteed even if the value stays
within the regulating pressure range.
