NOTES
1. Coil operating power
Pure DC current should be applied to the
coil. The wav e 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
20 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 RJ relays are highly sensitive polarized relays, their characteristics will be affected by a strong e xternal magnetic field.
Avoid using the rela y 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. Conditions for operation, transport
and storage conditions
1) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay:
(1) T emper ature:
–30 to +70°C –22 to +158°F
(However, tolerance range is –30 to
+60°C –22 to +140°F if package is carried
as is.)
(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

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 prob-
lems such as sticking of movab le parts or
operational time lags.
4) Low temperature, low humidity en vironments
The plastic becomes brittle if the relay is
exposed to a low temperature, lo w humidity environment for long periods of time.
5) Storage procedures for surface-mount
terminal types
Since the relay is very sensitive to humidity, it is packed in humidity-free, hermetically sealed packaging. When storing the
relay, be careful of the following points:
(1) Be sure to use the relay immediately
after removing it from its sealed package.
(2) When storing the relay f or long periods
of time after removing it from its sealed
package, we recommend using a humidity-free bag with silica gel to prevent subjecting the relay to humidity.
Furthermore, if the relay is solder mounted when it has been subjected to excessive humidity , cr acks and leaks can occur .
Be sure to mount the relay under the required mounting conditions.

7. Soldering

In case of automatic soldering, the following conditions should be observed
(1) Position of measuring temperature

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 e xceed
the above mentioned soldering condition.
It is recommended to check the temperature rise of each portion under actual
mounting condition before use.
2) Standard PC board terminal
Please meet the following conditions if
this relay is to be automatically soldered.
(1) Preheating: Max. 100°C 212°F (termi-
nal solder surface) for max. 60 seconds
(2) Soldering: Max. 250°C 482°F for max.
5 seconds
The effect on the relay depends on the actual substrate used. Please v erify the substrate to be used.
3) Hand soldering
Please meet the following conditions if
this relay is to be soldered by hand.
(1) Wattage: 30 to 60 W
(2) Tip temperature/time: 280 to 300°C
536 to 572°F for max. 5 seconds
The effect on the relay depends on the actual substrate used. Please v erify the substrate to be used.
4) Avoid high frequency cleaning since
this may adversely affect relay characteristics. Use alcohol-based cleaning solutions when cleaning relays.

Insertion loss compensation

subtracting the insertion loss of shortcircuit the Com and the NC (or NO). (signal path and two connectors)

1) The switching lifetime is defined under
the standard test condition specified in the
JIS* C 5442-1996 standard (temperature
15 to 35°C 59 to 95°F, humidity 25 to
75%). Chec k 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.
• When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.

• High-frequency load-operating
When high-frequency 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 cor-
rode metal materials.
Three countermeasures for these are listed
here.
(1) Incorporate an arc-extinguishing circuit.
(2) Lower the operating frequency
(3) Lower the ambient humidity
2) Use the relay within specifications such
as coil rating, contact rating and on/off
service life. If used beyond limits, the rela y
may overheat, generate smoke or catch
fire.
3) Be careful not to drop the relay. If accidentally dropped, carefully check its appearance and characteristics before use.
4) Be careful to wire the relay correctly.
Otherwise, malfunction, overheat, fire or
other trouble may occur.
5) If a relay stays on in a circuit for many
months or years at a time without being
activated, circuit design should be reviewed so that the relay can remain nonexcited. A coil that receives current all the
time heats, which degrades insulation
earlier than expected. A latching type relay is recommended for such circuits.
6) The latching type rela y is shipped in the
reset position. But jolts during transport or
impacts during installation can change
the reset position. It is, therefore, advisable to build a circuit in which the relay
can be initialized (set and reset) just after
turning on the power.
7) If silicone materials (e.g., silicone rubbers, silicone oils, silicone coating agents,
silicone sealers) are used in the vicinity of
the relay , the gas emitted from the silicone
may adhere to the contacts of the relay
during opening and closing and lead to
improper contact. If this is the case , use a
material other than silicone.
8) We recommend latching type when using in applications which involve lengthy
duty cycles.
