FEATURES

• Breakdown voltage between contacts and coil: 2,000 V

• Surge withstand between contacts and coil: 2,500 V

• High contact capacity: 2 A 30 V DC

• Surface-mount type available

SPECIFICATIONS

Contact

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.

Remarks

* Speciﬁcations will vary with foreign standards certiﬁcation ratings.
