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 Refer to 6. Conditions for operation, transport and storage mentioned in
*3 The maximum ambient temperature allows for coil temperature rise at maximum allowable coil voltage.
As for the applicable range of continuous carrying current against temperature, please refer to “Maximum value of continuous carrying current” chart. (Page 4)
