Safety Precautions
Follow the instructions to prevent injuries and
accidents.
• Avoid use beyond the specifications.
Such use may generate abnormal heat, smoke and fire.
• Correctly connect terminals according to the pin
arrangement in the specifications. Misconnection
may invite unexpected malfunction, abnormal heat,
smoke and fire.
• For safety-sensitive use, arrange appropriate
protective circuits and protection devices.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.

Light Sensor (AMS3)
CAUTIONS FOR USE
■ Applying stress beyond absolute maximum rating
When voltage and current values of each terminal
exceed absolute maximum rating, overvoltage and
overcurrent may deteriorate the internal element. In
extreme cases, such excess may melt wires or damage
the silicon P/N junction. Design the product not to
exceed the absolute maximum rating even momentarily.
■ Recommended soldering conditions
<Through-hole type>
1) Recommended conditions
(1) Double-wave soldering method
T2
T1 =
T2 =
t2 =
t2+t3
T1
■ Deterioration and damage by static electricity discharge
The phenomenon, deteriorating the internal element, is
generally called electrostatic breakdown. It is caused by
discharge of static electricity, arisen from multiple factors,
to each terminal. Once unpacked, perform antistatic
countermeasures and follow the instructions below.
1) Operators must wear antistatic cloths and human
body grounding devices, and have the protective
resistance of between 500 kΩ and 1 MΩ.
2) Cover the surface of workbench by electroconductive metal plates and ground measuring
instruments and jigs.
3) Use the soldering iron which has a small
leakage current or ground the soldering
tip. (The soldering iron for a low voltage is
recommended)
4) Ground the assembling equipment.
5) When packing printed-circuit boards and
devices, avoid polymeric materials, which
have electrification characteristics, such as
expanded polystyrene and plastic.
6) 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.
■ When the power is supplied, the current flowing into the
sensor varies in order to stabilize the internal circuit.
■ Storage
The sensor is in the transparent resin package. Due to
its sensitivity to humidity, the package is moisture-proof.
When storing the sensor, follow the instructions below.
1) Promptly use after opening. (within a week,
below 30 °C 86 °F/60 % R.H.)
2) Once unpacked, preserving in a moisture-proof
manner, such as keeping in a moisture-proof
bag with silica gels, is recommended for longterm storage. (use within 3 months)
3) E x t re m e l y b a d s t o r a g e c o n d i t i o n s m a y
deteriorate solderability or characteristics,
and defect the appearance. Recommended
conditions of the storage place are below.
• Temperature : 0 to 30 °C 32 to 86 °F
• Humidity : Below 60% R.H. (Avoid freezing
and dew condensation)
• Atmosphere: Low-dust and free from noxious
chemicals such as sulfurous acid gas
✽ During soldering, when adding thermal stress
in a moisture absorbing state, moisture
evaporates, swells and generates stress to
the internal package. To avoid swellings and
cracks in the surface of the package, follow
soldering conditions below.

120 °C 248 °F
Below 260 °C 500 °F

(2) Soldering method
Tip temperature : 350 to 400 °C 662 to 752 °F
Wattage
: 30 to 60 W
Soldering time : Less than 3 sec.
2) Keep the soldering part at a distance of 3 mm
0.118 inch or more from the root of the lead.
■ Mounting
1) When various packages are on one circuit board,
temperature rise of the lead largely depends
on the package size. Keep temperature of the
soldered terminals of the products below the
previously mentioned specifications. Before use,
check the performance with actual equipment.
2) I f m o u n t i n g c o n d i t i o n s a re b e y o n d t h e
specifications above, such use may decrease the
resin strength, increase mismatching in the thermal
expansion coefficient of each component material,
generate cracks in the package and break the
bonding wire. Please consult us before use.
■ Cleaning
For flux cleaning, immersion cleaning by ASAHIKLIN
AK-225 is recommended. If using ultrasonic cleaning for
unavoidable reasons, implementation conditions should
not be beyond the specifications below. Before use,
check and ensure that there is no defect.
• Frequency
: 27 to 29 kHz
• Ultrasonic outlet : Below 0.25W/cm2 ✽
• Cleaning time
: Less than 30 sec.
• Cleaning solvent : ASAHIKLIN AK-225
• Others
: I n o rd e r t o p re v e n t t h e
printedcircuit board and
elements from contacting with
ultrasonic oscillator, clean
the flux while the sensor is
suspended in the solution.
✽ Ultrasonic outlet per unit area (bottom area) of
cleaning tank
■ Transportation
Excessive vibration during transport may deform the
lead or damage the sensor. Carefully handle the
exterior and interior boxes.
■ Avoid use in the highly-humid or dusty environment,
the corrosive gas, an environment where organic
solvent can be adhered.
■ Lead-forming and cuttings
1) Before soldering, perform lead forming at
normal temperature.
2) When forming or cutting the lead, keep the spot at
a distance of 3 mm 0.118 inch or more from the
root of the lead.
3) When forming and cutting, fix the root of the lead.
4) Avoid mounting which may cause stress on the
root of the lead.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
