■
Before use, carefully check theperformance and
quality under actualuse conditions to enhance stability.
■ Mounting
• Use the land of the printed-circuit boardon which
the sensor is securely fixed.
t1
• A large noise on the power supply may cause
malfunction. Place the recommended capacitor near
the sensor (within 20 mm 0.787 inch of the wiring
pattern length) between sensor input terminals
(VDD-GND) to secure power superimposed noise
resistance. Test with the actual machine and re-
select the capacitor with optimal capacitance.
• Prevent the metal part of other electronic
components from contacting with the sensor
body as the upper face (where part numbers are
imprinted) of the sensor is GND.
■ Wire connection
• Correctly wire as in the connection diagram.
Reverse connection may damage the product and
degrade the performance.
• Do not connect wires with NC terminals. Such
connection may damage the sensor.
■ Cleaning
Avoid ultrasonic cleaning as this maycause
disconnection of the wire.
■ Soldering
■ Environment
• When soldering, avoid the external thermal
influence. Heat deformation may damage the
sensor or deteriorate its performance.
• Use the non-corrosive rosin flux.
• Avoid use and storage in the corrosive gas (organic
solvent, sulfurous acid and hydrogen sulfide gases)
which negatively affects the product.
• When installing the sensor, also install the
capacitor as in the connection diagram.
• Use surge absorbers as applying the external
surge voltage may damage the internal circuit.
• Malfunction may occur near electric noises from
static electricity, lightning, broadcast or amateur
radio stations and mobile phones.
1) Manual soldering
• Raise the temperature of the soldering tip
between 350 and 400 °C 662 and 752 °F
(30 and 60W) and solder within 3 seconds.
• The sensor output may vary if the load is
applied on the terminal during soldering.
• Keep the soldering tip clean.
• Avoid use in a place where these products come
in contact with water.
2) Reflow soldering
Below are recommended temperature profiles/
conditions of reflow.
• Avoid use in an environment where these products
cause dew condensation. When water attached to
the sensor chip freezes, the sensor output may be
fluctuated or damaged.
• When printing cream solder, the screen
printing method is recommended.
• For the foot pattern, see the recommended
diagram of the printed-circuit board.
• Do not apply high-frequency oscillation, such as
ultrasonic waves, to the product.
• Carefully align the terminal with the pattern
as self-alignment may not be reliable.
• The temperature of the profile is the value
measured near the terminal on the printed-
circuit board.
■ Other precautions
These specifications are for individual components.
Before use, carefully checkthe performance and quality
under actual use conditions to enhance stability.
• Once the individual sensor is dropped, do not
use. Drop may cause functional disorders.
• Misconnection and the wrong acceleration sensing
range may invite the risk of accidents.
• After reflowing, when performing reflow
soldering on the back surface of the circuit
board, use an adhesive to fix the board.
3) Rework soldering
• Complete rework at a time.
•
Ensure that using acceleration is within the rated range.
Use beyond the range may damage the product.
• Use a flattened soldering tip when
performing rework on the solder bridge.
Do not add the flux.
• Follow the instructions below as static electricity
may damage the product.
• Keep the soldering tip below the temperature
described in the specifications.
(1) For storage and transportation, avoid plastic
containers which are easily electrified.
4) After soldering, do not apply stress on the soldered
part when cutting or bending the circuit board.
5) Prevent human hands or metal pieces from
contacting with the sensor terminal. Such
contact may cause anomalous outlets as the
terminal is exposed to the atmosphere.
6) After soldering, prevent chemical agents
from adhering to the sensor when applying
coating to avoid insulation deterioration of the
circuit board.3. Maximum applied pressure
The maximum pressure that can be applied
to the pressure sensor, after which, when
the pressure is returned to below the rated
pressure range, the specifications of the
pressure sensor are guaranteed.
(2) When storing and transporting the sensor,
choose the environment where static electricity
is hardly generated (e.g., humidity between 45
and 60 %) and protect the product by using
electroconductive packaging materials.
(3) Once unpacked, perform antistatic countermeasures.
• Operators handling sensors must wear antistatic
cloths and human body grounding devices.
• Cover the surface of workbench by electro-
conductive plates and ground measuring
instruments and jigs.
• Use the soldering iron which has a small
leakage current or ground the soldering tip.
• Ground the assembling equipment.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

(4) Use surge absorbers as applying the external
surge voltage may damage the internal circuit.
(surge resistance: power supply voltage as in
the absolute maximum rating)
■ Special notes
We exert maximum efforts for quality control of the
product, Please mind also about the following.
1) To prevent occurrence of unexpected
circumstances, please inform us of the
specifications of your product, customers,
use conditions and details of the attachment
position.
2) Have sufficient margin values of driving/
performance guarantee described in the
specifications and apply safety measures with
double circuits, if serious effects on human
lives or property are predicted due to a quality
failure of the product. Those countermeasures
are also for the product liability.
3) A warranty period is one year after the delivery
to your company. Quality assurance is limited
to the items and the scopes described
in the specifications. If a defect is found
after the delivery, we will promptly provide
a replacement or change/repair the defect
part at the place of delivery in good faith.
Exceptions are below.
• Damages by a failure or a defect which
arose after the delivery.
• After the delivery, when storing and
transporting, if conditions other than
conditions in the specifications are applied to
the product.
• Damages by unforeseen phenomenon which
cannot be predicted with the technologies
available at the time of delivery.
• Damages by natural and anthropogenic
disasters, such as earthquake, flood, fire
and war, which are beyond our reasonable
control.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
