Ordering Information

Complies with ROSH for environmental protection.
Special ordering is allowed for other nominal voltages.

Notes and Recommendations

The default status of the relay contact is closed (reset). It may change to open due to transit or mounting; check and reset if necessary.
Ensure excitation voltage reaches rated voltage without exceeding 1 minute. For double coil relays, do not apply voltage to both coils simultaneously.
Terminals without twisted copper cable should not be tin soldered or wrenched.
Do not use relays that have undergone electrical endurance testing.

Outline dimensions and circuit diagram Remark: The tolerance didn’t mark on drawings. When dimension is≤1mm,the tolerance should be less than ±0.2mm ; when dimension is between 1-5mm, the tolerance should be less than ±0.3mm; When dimension is ≥5mm, the tolerance should be less than ±0.5mm. Note: 1. The default status of the relay contact is closed( Reset), it maybe change to “open” due to transit or relay mounting, please check the contact status when using, and reset the relay contact status on request if necessary. 2.In order to make sure the contact “ open” or “closed” status, the excitation...
