1. Do not drop, bump, or apply excessive impacts (100
m/s
2
) while handling. Although the body of the sen-
sor 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 malfunc-
tion. When handling, hold the body of the sen-
sor—do not dangle it from the cord.
3. Do not exceed the screw-in torque of 7 to 9 N·m
when connecting the pipe to the switch. Exceeding
these values may cause the switch to malfunction.
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. Consult 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. Connec-
tions should be done while the power is turned off.
2. Do not attempt to insert or pull the pressure sen-
sor or its connector when the power is on. A
switch output malfunction may occur.
Connection
Warning
1. Wire separately from power lines and high voltage lines,
avoiding wiring in the same conduit with these lines. Mal-
functions may occur due to noise from these other lines.
2. If a commercial switching regulator is used, make
sure that the F.G. terminal is grounded.
Caution
1. This pressure switch is CE marked; however, it is
not equipped with surge protection against lightning.
Lightning surge countermeasures should be applied
directly to system components as necessary.
2. This pressure switch does not have an explosion
proof rating. Never use in the presence of an explo-
sive gas as this may cause a serious explosion.
3. Do not use in an environment where static electri-
city can cause problems, otherwise system failure
or malfunction may result.
Operating Environment
Warning
1. Mounting and removing with panel mount adapter
2. Mounting with brackets
• Mount a bracket to the using two M3 x 5L mounting screws and
install on piping. The switch can be installed horizontally de-
pending on the installation location.
To release push the claws
outward as shown on the pic-
ture, and pull back towards
Caution
Mounting
• 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 pres-
sure with your thumb to the lever and unhooking it from the jack.
• When using bracket B, take piping dimensions into considera-
tion for installation.
• Do not attempt to insert or pull the pressure sensor or its con-
nector when the power is on. A switch output malfunction may
occur.
Connection/Removal of Connector
• Cut the tube perpendicularly.
• Hold the tube and insert it into the One-touch fitting carefully
and securely all the way to the bottom.
Piping
The tightening
torque for bracket
mounting screw
should be 0.5 to
0.7 N·m.
