2. Specifications
Notes: *1 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the
actual load.
(SX relays are available for low level load switching [10V DC, 10mA max. level])
*2 Half-wave pulse of sine wave: 11ms; detection time: 10µs
*3 Refer to 6. Conditions for operation, transport and storage mentioned in AMBIENT ENVIRONMENT.
