For high power type, we suggest to select flux proof version for better heat distribution if the relay will not exposed in high humidity/sulphide/dust environment.
For standard type, materials used already meet Class B insulation requirements.
When ordering, add rated coil voltage to model.
PRECAUTIONS REGARDING COIL INPUT
For the operation of AC relays, the power source is almost always a commercial frequency (50 or 60 Hz) with standard voltages of 6, 12, 24, 48, 120, 230 and 240VAC. Due to this, when the voltage is ohter than the standard voltage, the product becomes special model.
PRECAUTIONS REGARDING CONTACT
For the operation of AC relays, the power source is almost always a commercial frequency (50 or 60 Hz) with standard voltages of 6, 12, 24, 48, 120, 230 and 240VAC. Due to this, when the voltage is ohter than the standard voltage, the product becomes special model.
PRECAUTIONS REGARDING SOLDERING CONDITION
We recommend wave solder, the recommended temperature is 240°C 464°F to 260°C 500°F, and the time is 2s to 5s, time should no longer than 2s when temperature reach 250°C 500°F or above.
