Note: 1. The data shown above are initial values.
2. The contact resistance was measured with 0.1 A at 5 VDC using the fall-of-potential method.
3. The operate time and release time was measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C.
4. For the step signal, set a minimum pulse time of 100 ms for both the ON time and OFF time.
5. The electrical endurance was measured at an ambient temperature of 23°C.
6. This value was measured at a switching frequency of 120 operations per minute.
