Notes:
❇1This value can change due to the switching frequency, environmental conditions,
and desired reliability level, therefore it is recommended to check this with the ac-
tual load. (SX relays are available for low level load switching [10 µA 1 mV DC –
10 mA 10 V DC])
❇2The upper limit for the ambient temperature is the maximum temperature that
can satisfy the coil temperature rise. Under the packing condition, allowable tem-
perature range is from –40 to +70°C –40°C to +158°F.
