∗∗
∗Product specifications
•Operate the pressure sensor with the specified voltage.
Operation with a voltage beyond specifications can cause malfunction or damage of the pressure sensor.
Insufficient supply voltage may not drive a load due to a voltage drop inside the pressure sensor.
Verify the operating voltage of the load before use.
•Use at pressure within the specified range.
Otherwise it can cause damage to the pressure sensor and an abnormal measurement.
•Do not exceed the specified maximum allowable load.
Otherwise it can cause damage or shorten the lifetime of the pressure sensor.
•Reserve a space for maintenance.
Remember to leave space for maintenance when designing the piping plan.

♦Product handling
∗
∗∗
∗Installation
•Do no drop, hit or apply excessive shock (300m/s2) to the pressure sensor.
Otherwise it can result in damage to the pressure sensor causing failure or malfunction.
•Do not pull lead wires or lift the body with lead wires. (The pulling force is 50N)
Hold the body when handing. Otherwise it can result in damage of the pressure sensor causing failure o
r
malfunction.
•Follow the specified tightening torque. (Appropriate tightening torque 0.5 to 0.7N.m)
Excessive tightening torque can break the pressure sensor. Insufficient tightening torque can displace the
pressure sensor from the original position or loosen the mounting screws.
•Do not insert wires or other foreign matter into the pressure measurement port.
It can damage the pressure sensor causing failure or malfunction.
•Connect frame-ground terminal (FG terminal) to the ground when using a switching power supply.
•Insert a noise filter (power line noise filter, ferrite core, etc.) between the switching power suppl
y
and this pressure sensor.
•Extend connection of air tube to safety place without exposure to splashing water and dust.
•Do not apply unnecessary forces such as twisting, pulling, moment loads, etc. on fittings or tubing.
•When the tube of other company is used, ensure the tube has the accuracy of inside diamete
r
within ±0.3mm.
•Insert into pipe precisely so that air tube won’t come off. (Tensile strength is approx.25N at 8mm
inserted.)
∗
∗∗
∗Wiring
•Do not bend or apply tensile stress to lead wires repeatedly.
Wiring with repetitive bending stress or tensile stress can cause breakage of the lead wires.
Replace the product when damage to a lead wire is observed.
•Connect wires and cables correctly.
Miswiring can break the pressure sensor depending on a miswired circuit.
•Do not connect wires while the power is on.
Otherwise it can break the circuit inside the pressure sensor causing malfunction.
•Do not lay wires or cables with power cable or high-voltage cable in the same wiring route.
Otherwise the wires to the pressure sensor can be contaminated with noise or induced surge voltage from
power lines or high voltage lines causing malfunction. Lay the wires to the controller to a wire duct or in a
protective tube other than those for power lines or high voltage lines.
•Verify the insulation of wiring.
Poor insulation (interference with other circuit, poor insulation between terminals and etc.) can introduce
excess voltage or current to the controller causing damage.
•Keep wiring as short as possible to prevent noise and surge voltage from being induced.
Do not use a cable longer than 10m. Consult with SMC for the use with a cable longer than 10m. Connect the
0V DC wire (blue line) directly or as close as possible to the 0V DC terminal of the DC power supply.

•The direct-current power supply to combine should use UL authorization power supply which is
the class 2 power supply based on UL 1310 or the power supply is using the transformer of a
class 2 based on UL 1585.
∗
∗∗
∗Environment
•Do not use the product in an atmosphere containing corrosive gas, chemicals, sea water, wate
r
or vapor, or in a place where there is a possibility of adhesion of those substances to the product.
It can cause failure or malfunction.
•Avoid exposure of this product to direct sunlight.
Use sunshades if the product is exposed to direct sunlight. Otherwise it can cause failure or malfunction.
•Do not use in a place where water, oil or chemicals splashes.
Otherwise it can cause failure or malfunction.
•Do not use a pressure sensor nearby a place where electric surges are generated.
Internal circuit elements of the pressure sensor can deteriorate or break when equipment generating a
large surge (electromagnetic lifter, high frequency induction furnace, motor, etc.) is located near the
pressure sensor. Provide surge preventives, and avoid interference.
•Do not apply the pressure sensor to the load that generates electric surge voltage.
Relays or solenoid values generate electric surge voltage. When applying the controller to drive these
loads directly, use the product equipped with surge absorber.
•The product is not resistive to a lightning surge defined in CE marking. Take measures to protec
t
against a lightning surge at the load side.
•Prevent foreign materials such as remnant of wires from entering this product.
Take proper measures for the remnant not to enter the pressure sensor in order to prevent failure o
r
malfunction.
•Do not expose the pressure sensor to vibration (less than 100m/s2), and impact (less than
300m/s2).
Otherwise it can cause damage or malfunction.
•Follow the specified ranges of the operating fluid and maintain ambient temperatures.
The operating fluid and ambient temperatures should be in the range of 0 to 50°C. When operating at lo
w
temperature of 5°C or below, breakage or malfunction can occur to the pressure sensor due to freezing o
f
condensed water in the pressurized air. Take preventive measures against freezing. Do not use the
pressure sensor in a place where temperature suddenly changes even if it stays within the specified
range.
•Do not expose the pressure sensor to heat radiation from a heat source located nearby.
It can cause malfunction.
∗
∗∗
∗Adjustment and Operation
•Do not short-circuit the load.
However, excess current can damage the pressure sensor when a load is short-circuited.
•A warm-up time of 20 to 30 minutes is needed for detection of slight pressure.
∗
∗∗
∗Maintenance
•Before performing maintenance, make sure to turn off the power supply.
Otherwise an unexpected operation of the system component can occur.
•Perform maintenance and check regularly.
Otherwise an unexpected malfunction of the system can occur due to a malfunction of the pressure
sensor.
•Perform a proper functional check after maintenance.
Stop operation when an abnormality is observed such that the device does not work properly.
Otherwise an unexpected malfunction of the system component can occur.
•Do not use solvents such as benzene or thinner to clean the pressure sensor body.
It can damage the surface of the body and erase the indication on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and
fully squeezed, then wipe up the stains again with a dry cloth.
