Guide to Applications
| 1. |
When connecting coils, refer to the pin configuration to prevent misoperation or malfunction. |
| 2. |
The latch type relay should be initialized at the appointed position (set or reset position) when using, and should be energized or deenergized to the specified polarity to avoid wrong operations by reversed contact state. |
| 3. |
Ultrasonic cleaning is not recommended to keep contact performance reliable. Alcohol based solvents are available as proper solvents. |
| 4. |
Pressurized stress on the relay cover may affect reliable operation. |
| 5. |
Minimum contact load of the relay is 10 mVdc, 10 µA. This value is a reference value in the resistance load. Minimum capacity changes depending on switching frequency and environment temperature and the load. |
