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.
2. Voltage applied to coil
To ensure reliable operation, please apply
nominal voltage to the coil. Beware of the
fact that pick-up voltage and drop-out
voltage vary depending on the ambient
temperature and conditions.
3. Operating life
Operating life varies depending on the
type and load of the coil drive circuit, as
well as factors like the operating
frequency, operating phase and ambient
atmosphere, so please check with actual
equipment.
4.Soldering
We recommend the following soldering
conditions.
1) Automatic soldering
* Preheating: 100C
212F
, within 2 mins
(PC board solder surface)
* Soldering: 260C
500F
, within 5 s
2) Hand soldering
* Iron tip temperature: 280 to 300C
536
to 571F
* Soldering iron: 30 to 60W
* Soldering time: Within 5 s
5. Usage, transport and storage
conditions
1) Ambient temperature, humidity, and
atmospheric pressure during usage,
transport, and storage of the relay:
(1) Temperature:
40 to +85C
40 to +185F
(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
temperatures are lower than 0C
32F
.
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.
6. Others
1) If in error the relay has been dropped,
the appearance and characteristics
should be checked before use without fail.
2) Please do not use the coating material
of organic system which contains solvents
such as xylene and toluene for this
product.
