Alarms, Buzzers, and Sirens: PKM33EPH1201C

Alarms, buzzers, and sirens are part of a wide range of products that are used to alert people to various situations by generating a noise or warning sign. The PKM33EPH1201C is a piezoelectric sounder that provides an effective sound notification solution. This article aims to discuss the application field and working principle of the PKM33EPH1201C.

Application Field

The PKM33EPH1201C is designed to be a general-purpose sounder for various application fields. It can be used in home security systems, medical equipment, gas detection systems, industrial machinery, computer peripheral devices, and office supplies, to name a few. The sounder also excels in providing an audible alert for low-current consumption pre-alarm notification in distributed fire detection systems.

The sounder is integrated with an influence and rotating technology, providing consistent sound performance even in environments with high and low-power loads. The sounder is designed to be thin, making it easily mountable in aircraft, vehicles, and other products that require space-efficient components. The sounder also has a wide operating temperature range, making it compatible with both hot and coldenvironmental conditions.

Working Principle

The PKM33EPH1201C is a piezoelectric sounder that produces sound waves by converting electrical energy into sound energy. It comprises of two parts: a piezoelectric transducer and a permanent magnet. The transducer is made from a polymer material that vibrates to generate sound waves, while the permanent magnet helps to amplify the sound.

When electrical energy is applied to the transducer, it vibrates, producing sound waves. The permanent magnet helps to create a magnetic field, which helps to increase the energy of the sound waves. The sounder can also change its sound level by varying the strength of the magnetic field, allowing it to be used for applications like low-power audio systems or warning notification systems.

The sounder also features an external volume control which can be set according to the desired level of sound. It is capable of producing audible sound levels of up to 103 dBa. In addition, the sounder is designed to be energy efficient, with a low power consumption of 40mA and a standby current of 2mA. This allows it to be used in power-sensitive applications, such as battery-powered devices.

Conclusion

The PKM33EPH1201C is a piezoelectric sounder that produces audible sound notifications for various applications and environments. The sounder is designed to be thin, integrated with influence and rotating technology, and is capable of producing sound levels of up to 103 dBa. In addition, the sounder is energy efficient and requires only a low-current consumption of 40mA. These features make the PKM33EPH1201C an ideal choice for applications in military, medical, and safety applications.
