Note: 1. Rated current values are determined according to the testing conditions. The above ratings were obtained by
conducting tests under the following conditions.
(1) Ambient temperature: 20±2C°
(2) Ambient humidity: 65±5% RH
(3)Operating frequency: 20 operations/minute
2. Minimum applicable load: 10 mA at 5 VDC

Note: 1. Do not allow the load current to exceed the rated value.
2. The contact ON/OFF timing is not synchronized. Confirm performance before application.
3. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The
contact surfaces will become rough once they have been used and contact reliability for smaller loads may be
reduced.
