* Condensing ;
Condensing occurs when the relay is exposed to sudden temperature change in a high-temperature,
high-humidity atmosphere. This may cause some troubles like insulation failure.

* Freezing ;
At temperature below 0°C, moisture may freeze. This may lead to some trouble like sticking of the
moving portion of the relay or delayed operation.
* Low-temperature, low-humidity atmosphere ;
If the relay is exposed to a low-temperature, low-humidity atmosphere for a long time, its
plastic parts may become brittle and fragile.
11-2. Operating voltage range ; 20VDC to 32VDC
12. This relay shall not be cleaned by the ultrasonic cleaning for it affects the relay characteristics. :
Please use an alcohol - or water - based cleaning solvent.
13. Automatic soldering according to the following conditions.
1.Preheat : Max. 100°CMax. 120s
2.Soldering : Max. 260°CMax. 5s
14.CAUTION FOR USE
14-1. Regarding cautions for use and explanation of technical terms, please refer to our general catalogue
14-2. For secure operations, the voltage applied to coil should be nominal voltage. In addition, please note
that pick-up and drop-out voltage will be changed according to the ambient temperature and
using condition.
14-3. Lifetime is dependent on the coil driving circuit, load type, operating frequency, on/off phase and
ambient conditions. Check lifetime under the actual condition.
The following load conditions may reduce lifetime:
When switching loads that cause contact arcing at high frequencies, the resulting arc energy
may synthesize HNO; which causes contact corrosion. To prevent this, take one or more of
the following actions:
1.Use a spark suppressor across the contacts
2.Reduce the on/off frequency
3.Reduce the ambient humidity
14-4. Ifthe relay is used while exceeding the coil rating, contact rating or cycle lifetime, this may result
in the risk of overheating, smoke or combustion.
14-5. If the relay is dropped onto a hard surface, it should not be used again. If it is used, be sure to check’
electrical/mechanical characteristics and the external conditions beforehand.
14-6, Please contact your nearest sales office when AC load gets applied to this relay. Careful handling is
required for switching AC load with this relay.
14-7. Take care to avoid cross connections as they may cause malfunctions, overheating or combustion.
