How to Use
Install the ADW1112TW relay onto your circuit board using through-hole mounting. To switch states, apply a brief 12V DC pulse to the coil. Since it is a latching relay, it consumes power only during state changes—not while maintaining its position. Ensure correct polarity and pulse width for reliable operation in your application.
Cautions
- Do not apply continuous voltage to the coil
- Observe correct polarity when triggering coil
- Avoid mechanical stress during soldering
- Operate within the specified voltage and temperature range
- Ensure proper insulation to prevent short circuits
- Protect from moisture and contaminants
