Black AC Type Magnetic Door Buzzer , 2048 Hz Electromagnetic Buzzer With Soldered Wire

AC type Φ12*5.4mm 2048Hz electronic magnetic buzzer with soldered wire

Description:

A buzzer can be either AC or DC operated and can be mounted anywhere according to the need and purpose. When used as an alarm device, the buzzer is usually mounted on a control panel. The latest technological developments have led to using buzzers in sirens and signals for a wide range of applications.

When a lower frequency is required, an electromagnetic buzzer can fill the need. These are very common in automotive chimes and higher end clinical diagnostic devices. 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:

Widely used in quartz crystal clock, air-conditioner instrument, telephone, BP, copycat, alarm, instrument and apparatus, UPS power supply, motorcycle steering gear, electronic toy, computer terminal, and electronic watch.

Specifications:

There are two main types of buzzer: active and passive.

An active buzzer has a built-in oscillating source, so it will make sounds when electrified. But a passive buzzer does not have such source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it. The active buzzer is often more expensive than the passive one because of multiple built-in oscillating circuits.

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 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 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.

• Be careful not to drop the buzzer.
