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 30 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 RS 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.
5. Conditions for operation, transport 
and storage conditions
1) Temperature
• Single side stable standard and latching 
type: –40 to 70
°C 
–40 to 158
°F
• Single side stable silent type: 
–40 to 60
°C 
–40 to 140
°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 
Temperature and humidity range for 
usage, transport, and storage:
Single side stable standard 
and latching type
Single side stable silent type
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.
7) Storage requirements
Since the relay is sensitive to humidity, 
the surface-mount type is packaged with 
tightly sealed anti-humidity packaging. 
However, when storing, please be careful 
of the following.
(1) Please use promptly once the anti-
humidity pack is opened.
If relays are left as is after unpacking, 
they will absorb moisture which will result 
in loss of air tightness as a result of case 
expansion due to thermal stress when 
reflow soldering during the mounting 
process. (within one day, 30
°C and 
60%R.H or less)
(2) When storing for a log period after 
opening the anti-humidity pack, storage 
in anti-humidity packaging with an anti-
humidity bag to which silica gel has been 
added, is recommended.
*Furthermore, if the relay is solder 
mounted when it has been subjected to 
excessive humidity, cracks and leaks can 
occur. Be sure to mount the relay under 
the required mounting conditions.
6. Soldering
1) Please meet the following conditions if 
this relay is to be automatically soldered.
(1) Preheating: Max. 120
°C 
248
°F
 
(terminal solder surface) for max. 120 
seconds
(2) Soldering: Max. 260
±5°C 
500
±9°F
 for 
max. 6 seconds
*Relays are influenced by the type of PC 
board used. Please confirm with the 
actual PC board you plan to use.
*Please avoid reflow soldering.
2) Surface-mount terminal
In case of automatic soldering, the 
following conditions should be observed
(1) Position of measuring temperature
(2) IR (infrared reflow) soldering method
• Mounting cautions
Rise in relay temperature depends 
greatly on the component mix on a given 
PC board and the heating method of the 
reflow equipment. Therefore, please test 
beforehand using actual equipment to 
ensure that the temperature where the 
relay terminals are soldered and the 
temperature at the top of the relay case 
are within the conditions given above.
3) Please meet the following conditions if 
this relay is to be soldered by hand.
(1) 260
°C 
500
°F
 for max. 10 seconds
(2) 350
°C 
662
°F
 for max. 3 seconds
The effect on the relay depends on the 
actual substrate used. Please verify the 
substrate to be used.
(3) Avoid ultrasonic cleaning. Doing so 
will adversely affect relay characteristics. 
Please use alcohol-based cleaning 
solvents when cleaning relays.
