Mechanical Durability
## **General Data**
Insulation Resistance : Min.100MΩ at 500V DC
## **Dielectric Strength (Leakage current: 1mA)**
Between contacts : 550V AC, 1 min, 50/60Hz Between Coil and Contact : 550V AC, 1 min, 50/60Hz Operate Time : Max. 10ms. Release Time : Max. 10ms. Operating Temperature : -40°C to +85°C Storage conditions Storage Temperature : -40°C to +85°C Environments
: Store in locations where the product is not exposed to corrosive gas such as hydrogen sulfide gas or salty air. Store in locations where the product is not exposed to the direct ray of the sun and rain, snow.
Temperature Rise Coil : 70k max. by resistance method when 20A current is applied to contact and 110% of rated voltage to relay coil at 85°C.
Terminal Strength Tensile and pushing
: To be free from any abnormality in both the construction and characteristics after pushing and pulling the relay terminal 2mm from the body with below force for 10sec. The tensile force: 10N;
The pushing force: 2N.
Solderability : Solder should be finished 95% on dipped surface. Soldering bath of melted solder at 260±5°C for 5±1 sec.
Resistance to Soldering Heat : To be free from any abnormality in both the construction and characteristics after the terminals are dipped into the soldering bath 260±5°C for 10±1 seconds and then recover the relay in a room temperature and humidity for 2 hours. However, in the case of hand solder, it must be soldered within 3.5±0.5 seconds at 350±10°C.
