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: 100°C 

212°F

, within 2 mins 

(PC board solder surface)

* Soldering: 260°C 

500°F

, within 5 s

2) Hand soldering

* Iron tip temperature: 280 to 300°C 

536 

to 571°F

* 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 +85°C 

–40 to +185°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

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 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.

 

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.
