NOTES
1. Usage, transport and storage
conditions
1) Temperature:
–40 to +70°C
–40 to +158°F
2) Humidity: 5 to 85% RH
(Avoid freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.
3) Atmospheric pressure: 86 to 106 kPa

4) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of the relay insulation.
5) Freezing
Condensation or other moisture may
freeze on the relay when the
temperatures is lower than 0°C
32°F.
This
causes problems such as sticking of
movable parts or operational time lags.
6) Low temperature, low humidity
environments
The plastic becomes brittle if the relay is
exposed to a low temperature, low
humidity environment for long periods of
time.
2. Solder and cleaning conditions
1) Please obey the following conditions
when soldering automatically.
(1) Preheating: Within 120°C
248°F
(solder surface terminal portion) and
within 120 seconds
(2) Soldering iron: 260°C±5°C
500°F±41°F
(solder temperature) and
within 6 seconds (soldering time)
2) Since this is not a sealed type relay, do
not clean it as is. Also, be careful not to
allow flux to overflow above the PC board
or enter the inside of the relay.
3. Certification
1) This relay is UL and C-UL certified.
2) This relay is certified by TÜV as an
electromagnetic relay that complies with
VDE0435.
The terminals of this relay can only be
connected with solder.
4. Others
1) For precautions regarding use and
explanations of technical terminology,
please refer to “Relay Technical Data
Book”.
2) To ensure good operation, please keep
the voltage on the coil ends to
±5%
(at
20°C
68°F)
of the rated coil operation
voltage. Also, please be aware that the
pick-up voltage and drop-out voltage may
change depending on the temperature
and conditions of use.
3) Keep the ripple rate of the nominal coil
voltage below 5%.
4) The cycle lifetime is defined under the
standard test condition specified in the
JIS C 5442 standard (temperature 15 to
35°C
59 to 95°F,
humidity 25 to 75%).
The cycle life time is based on the
condition that a diode is connected in
parallel with the coil. The cycle life time
may be different if no diode was
connected to the coil.
Check this with the real device as it is
affected by coil driving circuit, load type,
activation frequency, activation phase,
ambient conditions and other factors.
Also, be especially careful of loads such
as those listed below.
(1) When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
(2) Highly frequent load-operating
When highly frequent opening and
closing of the relay is performed with a
load that causes arcs at the contacts,
nitrogen and oxygen in the air is fused by
the arc energy and HNO
3
is formed. This
can corrode metal materials.
Three countermeasures for these are
listed here.
• Incorporate an arc-extinguishing circuit.
• Lower the operating frequency
• Lower the ambient humidity
5) Heat, smoke, and even a fire may
occur if the relay is used in conditions
outside of the allowable ranges for the
coil ratings, contact ratings, operating
cycle lifetime, and other specifications.
Therefore, do not use the relay if these
ratings are exceeded.
6) If the relay has been dropped, the
appearance and characteristics should
always be checked before use.
7) Incorrect wiring may cause
unexpected events or the generation of
heat or flames.
