NOTES
Ⅵ Usage, transport and storage
conditions
1) Temperature:
–40 to +85°C –40 to +185°F (Allowable
range when in original packaging is –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 temperature
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.
Ⅵ Solder and cleaning conditions
1) Flow solder mounting conditions
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)
* Furthermore, because the type of PC
board used and other factors may
influence the relays, test that the relays
function properly on the actual PC board
on which they are mounted.
2) Reflow solder mounting (Pin-in-Paste
mounting) conditions

• Cautions to observe when mounting
temperature increases in the relay are
greatly dependent on the way different
parts are located a PC board and the
heating method of the reflow device.
Therefore, please conduct testing on the
actual device beforehand after making
sure the parts soldered on the relay
terminals and the top of the relay case
are within the temperature conditions
given above.
3) 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.
Ⅵ Cautions for use
1) For precautions regarding use and
explanations of technical terminology,
please refer to Group Catalog or our web
site.
2) Since this relay is polarized, please
observe the coil polarity (+ and –). Be
sure to connect as shown in the attached
product specifications diagram.
3) 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.
4) Keep the ripple rate of the nominal coil
voltage below 5%.
5) 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%).
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 are 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 HNO3 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
6) Minimum switching capacity provides a
guideline for low level load switching. This
value can change due to the switching
frequency, environmental conditions, and
desired reliability level, therefore it is
recommended to check this with the
actual load.
7) 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.
8) If the relay has been dropped, the
appearance and characteristics should
always be checked before use.
9) Incorrect wiring may cause
unexpected events or the generation of
heat or flames.
10) This relay can be oriented in any way
when installing. However, the set/reset
voltage and set/reset time, etc., may be
affected slightly by the orientation due to
the influence of gravitation. Therefore,
when evaluating the relay, please do so
with the relay placed in your intended
orientation.
11) In order to maintain consistent set/
reset pulse time of the latching type relay
so that positive movement is ensured
under ambient temperature fluctuations
and other usage conditions, we
recommend that you keep the coil
applied set/reset pulse width to 30 ms or
higher using the nominal coil voltage.
12) Relays are shipped in a ‘reset’ state.
During shipping and handling, however,
shocks may change the state to ‘set.’
Consequently, at time of use (at power
on) it is recommended to ensure that
circuits are returned to the desired state
(‘set’ or ‘reset’).
13) Do not use parts that generate
organic silicon. When present in the
vicinity, conduction failure may occur.
