NOTES
1. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be
rectangular. If it includes ripple, the ripple
factor should be less than 5%.
However, check it with the actual circuit
since the characteristics may be slightly
different. The nominal operating voltage
should be applied to the coil for more
than 10 ms to set/reset the latching type
relay.
2. Coil connection
When connecting coils, refer to the wiring
diagram to prevent mis-operation or
malfunction.
3. External magnetic field
Since RA relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
4. Cleaning
For automatic cleaning, the boiling
method is recommended. Avoid
ultrasonic cleaning which subjects the
relays to high frequency vibrations, which
may cause the contacts to stick.
It is recommended that alcoholic solvents
be used.

6. Soldering

under following condition.
Tip temperature: 280°C to 300°C 536°F
to 572°F.
Wattage: 30 to 60W
Soldering time: within 5s
In case of automatic soldering, the
following conditions should be observed
1) Position of measuring temperature
Surface of PC board where relay is mounted.
7. Conditions for operation, transport
and storage conditions
1) Ambient temperature, humidity, and
atmospheric pressure during usage,
transport, and storage of the relay:
(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.

Temperature rise of relay itself may vary
according to the mounting level or the
heating method of reflow equipment.
Therefore, please set the temperature of
soldering portion of relay terminal and
the top surface of the relay case not to
exceed the above mentioned soldering
condition.
It is recommended to check the
temperature rise of each portion under
actual mounting condition before use.
The soldering earth shall be performed
by manual soldering.

2) 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.
3) 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.
4) 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.
For general cautions for use, please
refer to the “General Application
Guidelines”.
