Coil data
• Operating characteristics such as ‘Operate voltage’ and ‘Release voltage’ are influenced by mounting conditions, ambient
temperature, etc.
Therefore, please use the relay within ± 5% of rated coil voltage.
• ‘Initial’ means the condition of products at the time of delivery.

NOTES
For cautions for use, please read “GENERAL APPLICATION GUIDELINES”.
HE-N Relays Cautions for use
Condition for use, storage and transportation
1. Ambient temperature：
-40〜+55°C
（When
coil holding voltage is 40 to 100%V of rated voltage.）
-40〜+85°C
（When
coil holding voltage is 50 to 60%V of rated voltage or
storage.）
2. Humidity：5〜85%RH
(Avoid icing when using at temperatures lower than 0°C.)
Note: In addition the humidity range depends on temperature.The allowable ranges are as
shown in the figure.
Temperature and humidity range for usage, storage and transport
［Coil
holding voltage 40〜100%V½
［Coil
holding voltage 50〜60％V½
Coil surge absorber
Please use a Varistor (ZNR) or Zener diode (ZD) which the
clamp voltage is at least 3 times larger than the rated voltage
for the purpose of the coil surge absorber.
If the clamp voltage is less than 3 times larger than the rated
voltage, electrical life of the relay specified in the
specifications shall not be secured because the contact
release speed becomes slower.
[Example 1: When Varistor (ZNR) is use]
Recommended
Varistor
Energy capability: Min. 1 J
（However,
please set up the value with
consideration of the worst value in use
condition.）
Min. 300% of rated voltage
(Recommended Varistor voltage is at 36 V or
more when the coil rated voltage is at 12 V.)
[Example 2: When Zener diode (circuit) is use]
(Set the clamp voltage at 36 V or more when the coil 1 rated
voltage is at 12 V.)
