DC type 12.8*12.8*10mm alarm SMD active magnetic buzzer 2400 ± 300Hz

Description:

The electromagnetic buzzer generally consists of a plastic housing with a metal diaphragm that is flexed by an electro- magnet. The main benefit of this design is the ability to obtain low frequencies in a small package. Drawbacks include mechanical wear, electrical noise, lower sound output, and large power consumption.

Application:

This kind of magnetic buzzer are widely used in bluetooth earphones, the anti-lost device, LED TV, remote control, camera, smart home furnishing and so on.

Precautions for use:

• Do not apply DC bias to the buzzer; otherwise insulation resistance may become low and affect the performance.

• Do not supply any voltage higher than applicable to the buzzer.

• Do not use the buzzer outdoors. It is designed for indoor use. If the buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture.

• Do not wash the buzzer with solvent or allow gas to enter it while washing; any solvent that enters it may stay inside a long time and damage it.

• Do not apply any mechanical force to the buzzer; otherwise the case may deform and result in improper operation.

• Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like.

• Be sure to solder the buzzer terminal at 350℃ max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver.

• Avoid using the buzzer for a long time where any corrosive gas (H2S, etc.) exists; otherwise the parts or sound generator may corroded and result in improper operation.

• Be careful not to drop the buzzer.
