Note 2) Vibration resistance: No malfunction occurred in a one-sweep test between 8.3 and 2000 Hz. Test was performed at both energized and
de-energized states to the axis and right angle directions of the main valve and armature (value at the initial state).
Impact resistance: No malfunction resulted from the impact test using a drop impact tester. The test was performed on the axis and right
angle directions of the main valve and armature for both energized and de-energized states (value at the initial state).
Note 3) If a restrictor (nozzle, etc.) is mounted on the outlet side piping, the pressure differential when ON is smaller. Be sure that the pressure
differential does not drop below 0.01 MPa.

Operation
When the pressure level exceeds the set value, the switch turns
ON.
When the pressure level decreases only the hysteresis from the
set value, the switch turns OFF.
With the factory default settings, when the pressure level ex-
ceeds 0.35 MPa, the switch turns ON. When the pressure level
becomes 0.34 MPa or less, the switch turns OFF.
When the operation shown in the Fig. below has no problem, use
the product with the factory default settings.
For details about how to set the pressure in window comparator
mode, refer to “Pressure Setting (Window comparator mode)” on
page 339.
<Operating procedure>
About measurement mode
In this measurement mode, the pressure is detected and displayed
or the switch is operated after the power has been turned ON.

(JIS B8392-1: 2000)
Operating Environment
Warning
1. Do not operate under the conditions listed below
due to a risk of malfunction.
In locations having corrosive gases, organic solvents, and
chemicals, or in locations in which these elements are likely to
adhere to the equipment.
In locations in which salt water, water, or water vapor could
come in contact with the equipment.
In locations that are exposed to direct sunlight. (Shield the
equipment from sunlight to prevent its resin material from ul-
traviolet ray degradation or overheating.)
In locations that have a heat source and poor ventilation.
(Shield the equipment from heat sources to protect it from
softening degradation due to radiated heat.)
In locations that are exposed to shocks and vibrations.
In locations with high humidity or a large amounts of dust.
2. When the product is used for blowing, use caution
to prevent the work from being damaged by en-
trained air from the surrounding area.
When the compressed air is used for air blow, the exhausted
air from the blow nozzle may have taken in airborne foreign
matter (such as solid particle, fluid particle) from the surround-
ing air. The foreign matter will be sprayed on the work, and the
airborne foreign matter may adhere to it. Therefore, use cau-
tion for the surrounding environment.

Piping
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
Install piping so that it does not apply pulling, pressing, bend-
ing or other forces on the module unit.
2. Cautions on use of One-touch fittings
1) Installation of tubing
(1) Cut the tubing perpendicularly, being careful not to dam-
age the outside surface. Use an SMC tube cutter “TK-1”,
“TK-2” or “TK-3”. Do not cut the tubing with pliers, nippers,
scissors, etc. If the tubing is cut with a tool other than the
tube cutter, the tubing cut surface becomes slant or flat-
tened.
The tubing cannot be connected securely, causing the tub-
ing disconnection or air leak after connection. Additionally,
cut the tubing with sufficient length.
(2) Grasp the tubing, slowly push it into the One-touch fitting
until it comes to a stop.
(3) Pull the tubing back gently to make sure it has a positive
seal. Insufficient installation may cause air to leak or the
tubing to release.
(4) Do not apply unnecessary forces such as twisting, pulling,
moment loads, vibratioin and impact, etc. on fittings or tub-
ing.
2) Removal of tubing
(1) Push the release button flange evenly and sufficiently to
release the tube.
(2) Pull out the tubing while keeping the release button de-
pressed. If the release button is not held down sufficiently,
the tubing cannot be withdrawn.
(3) To reuse the tubing, remove the previously lodged portion
of the tubing. If the lodged portion is left on without being
removed, it may result in air leakage and removal of the
tubing difficult.
Other Tube Brands
Caution
1. When tubing of brands other than SMC’ s are used,
verify that the tubing O.D. satisfies the following
accuracy;
1) Polyolefin tubing: Within ±0.1 mm
2) Polyurethane tubing: Within +0.15 mm, within –0.2 mm
3) Nylon tubing: Within ±0.1 mm
4) Soft nylon tubing: Within ±0.1 mm
Do not use tubing which does 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 tube
pulling out after connection.
The recommended tube for the clean fitting is polyolefin tube.
Other tubes can satisfy the performance in terms of leakage,
tensile strength, etc., but impair the cleanliness. Note this
point for use.

1. Confirm the specifications.
Products represented in this catalog are designed only for use
in compressed air systems. Do not operate at pressures or
temperatures, etc., beyond the range of specifications, as this
can cause damage or malfunction. Please contact SMC when
using a fluid other than compressed air.
2. Do not use the products described in this catalog
as “safety accessories” defined in 2.1.3 of Article 1
and in 1.4 of Article 3 in “Pressure Equipment Direc-
tive (97/23/EC)”.
In “Pressure Equipment Directive”, “safety accessories” are
defined as devices that are designed to prevent the pressure
equipment from exceeding its allowable limit value.
3. Check the set pressure range.
Be sure to install an appropriate safety device if it is predicted
that the output pressure exceeding the set pressure range
may cause the outlet equipment to break or malfunction.
4. Residual pressure relief when releasing the inlet
pressure
When releasing the inlet pressure with the outlet pressure set
at low pressure level, the outlet pressure may not be removed
(residual pressure relief).
Be sure to install an appropriate pressure relief circuit to re-
move the outlet pressure completely.
5. Product is used in the closed circuit or balance cir-
cuit at the outlet.
Please contact SMC since the product may not be used in
such circuit.
Design and Selection
Warning
Precautions on Regulator
1 .Set the regulator while verifying the displayed val-
ues of the inlet and outlet pressure gauges.
Turning the knob excessively can cause damage to
the internal parts.
2. Do not use a tool on the pressure regulator knob as
this can cause damage. It must be operated by
hand.
Warning
Adjustment
1. Check the inlet pressure before setting.
2. Set the outlet pressure range for the regulator in a
range that is 85% or less of the inlet pressure.
At this time, be sure to set the outlet pressure with-
in the set pressure range.
3. Adjust pressure after unlocking the pressure regu-
lator knob. If the steps are performed in incorrect
order, this may cause the handle to break or the
outlet pressure to fluctuate.
4. Rotating the knob clockwise increases the outlet
pressure, and rotating the knob counterclockwise
decreases the pressure. (Set the pressure in the in-
crease direction.)
5. Pressure gauge indicator adjusting procedure.
When adjusting the indicator on the pressure gauge, be sure
to follow the steps below since an open/close type lens is
