SAFETY PRECAUTIONS
Be sure to obey the following in order to
prevent injuries and accidents.
• Do not use the sensors under
CAUTIONS FOR USE
1. Applying stress that exceeds the
absolute maximum rating
If the voltage or current value for any of
the terminals exceeds the absolute
maximum rating, internal elements will
deteriorate because of the excessive
voltage or current. In extreme cases,
wiring may melt, or silicon P/N junctions
may be destroyed.
Therefore the design should ensure that
the absolute maximum ratings will never
be exceeded, even momentarily.
2. Deterioration and destruction
caused by discharge of static
electricity
This phenomenon is generally called
static electricity destruction. Static
electricity generated by various factors
flows through the terminal and occurs to
destroy internal elements. To prevent
problems from static electricity, the
following precautions and measures
should be taken when using your device.
1) Person handling sensor should wear
anti-static clothing and should be
grounded through protective resistance
of 500 kΩ to 1 MΩ.
2) A conductive metal sheet should be
placed over the work table. Measuring
instruments and jigs should be grounded.
3) When using soldering irons, either use
irons with low leakage current, or ground
the tip of the soldering iron. (Use of low-
voltage soldering irons is also
recommended.)

4) Devices and equipment used in
assembly should also be grounded.
5) When packing printed circuit boards
and equipment, avoid using high-polymer
materials such as foam styrene, plastic,
and other materials which carry an
electrostatic charge.
6) When storing or transporting sensor,
the environment should not be generated
static electricity (for instance, the
humidity should be between 45 and
60%), and sensor should be protected
using conductive packing materials.
3. Just after supplying voltage, please
note that current in the sensor will be
not constant until internal circuit
stability.
4. Storage
The sensors are transparent plastic
packages. They are sensitive to moisture
and come in moisture-proof packages.
Observe the following cautions when
storing.
1) After the moisture-proof package is
unsealed, take the sensors out of storage
as soon as possible (within 1 week
30°C 86°F/60% R.H.).
2) If the devices are to be left in storage
for a considerable period after the
moisture-proof package has been
unsealed, it is recommended to keep
them in another moisture-proof bag
containing silica gel (within 3 months at
the most).

3) Storage under extreme conditions will
cause soldering degradation, external
appearance defects, and deterioration of
the characteristics. The following storage
conditions are recommended:
• Temperature: 0 to 30°C
• Humidity: Less than 60% R.H.
• Atomosphere: No harmful gasses such

stress is applied to sensors that have
absorbed moisture, the moisture will
vaporize, swelling will occur, and the
inside of the package will become
stressed. This may cause the package
surface to blister or crack. Therefore,
please take caution and observe the
soldering conditions in the following
section.
