1. Do not drop, or apply excessive impact (980m/s
2
) while
handing. 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 49N. 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 13.6 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.

1. Mounting with panel mount adapter
2. Mounting with brackets
Mount a bracket to the using two M3 x 5L mounting screws
and install on piping with a hexagon socket cap screws. The
switch can be installed horizontally depending on the
installation location.
Caution
Mounting Method
1. Incorrect wiring can damage the switch and cause a malfun-
ction or erroneous switch output.
2. Turn off the power before connecting the wires.
3. Wire separately from power lines and high voltage lines,
avoiding wiring in the same conduit with these lines. Malfun-
ctions may occur due to noise from these lines.
4. If a commercial switching regulator is used, make sure that the
F.G. terminal is grounded.
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 it in the presence of an explosive gas as this may
cause a serious explosion.
Operating Environment
Warning
The tightening torque for bracket mounting
screw should be 0.98N
⋅
m or less.
1. Do not use in an environment with spattering liquid of oil or
solvent.
2. In an environment where the body of the switch is exposed to
water or dust, there is possibility of water or dust invasion of
the switch through the atmospheric release port. Insert a ø4
tube (with inside diameter of ø2.5) into the atmospheric
release port and pipe the other end to a place with no
spattering water or other liquid. Do not fold or clog the tube or
the pressure cannot be measured properly.

∗
Use SMC TU0425 (Material: Polyurethane, O.D.: ø4, I.D:

1. Use of toxic, corrosive or flammable gas.
The materials of the pressure sensor and fittings on the switch
are SUS630 and SUS304. Do not use toxic or corrosive
gas.
The switch is not protected against explosion. Do not use it
with flammable gas, either.
2. Compatible fluid
The fluid contact areas are SUS630 (pressure sensor) or
SUS304 (fittings). Use fluid that will not corrode the materials.
(For corrosiveness of fluid, consult the manufacturer of the
fluid.)
<ZSE60F/ISE60>
Helium leakage test
Helium leakage test is conducted on the welding parts. Use a
ferrule a ferrule by (Swagelok
fittings) as the TSJ fittings and
packing, ground, etc. by Cajon (VCR
fittings) as the URJ fittings.
If a ferrule, packing or ground by other manufacturers are to be
used, conduct helium leakage test before using those products.
