*1. The contact resistance was measured with 1 A at 5 VDC using the voltage-drop method.
*2. Not Including bounce time.
*3. The response time is the time it takes for the main contact to open after the input is turned OFF. Includes bounce time.
*4. The insulation resistance was measured with 500 VDC at the same places that the dielectric strength was checked.
*5. The durability is for an ambient temperature of 15 to 35℃ and an ambient humidity of 25% to 75%.
*6. Weight shown is for 24-VAC/VDC type. For 100 to 240-VAC type, add approximately 20 g.
