Alarms, buzzers, and sirens are used in a variety of applications to alert people and other systems to potential hazards or events. The PK-20N38PQ is a piezoelectric buzzer that can be used in a variety of applications. This article will discuss the application field and working principle of the PK-20N38PQ piezoelectric buzzer.

The PK-20N38PQ is commonly used as an audible warning device. It is typically used to alert people to dangerous situations such as gas leaks or fires. It can also be used in other applications such as in home security systems and motion detectors. In addition, it can be used as a backup alarm system in case the primary alarm fails.

The PK-20N38PQ is designed to be a reliable and cost-effective alarm system. It is a sealed, tamper-proof device with a long lifespan. The plastic housing of the device is rated for temperatures ranging from -40 degrees Celsius to +85 degrees Celsius. The device is also designed to be shock-resistant and can withstand vibrations up to 10g.

The PK-20N38PQ works by converting electrical signals into sound. It uses a piezoelectric element which oscillates when an electrical current is applied. The frequency of the oscillation determines the frequency of the sound produced. The PK-20N38PQ can produce a range of sound frequencies from 250Hz to 6kHz. It produces a sound pressure level of up to 100dB.

The PK-20N38PQ can be used in a variety of applications. It can be used as an audible warning to alert people to dangerous situations. It can also be used in motion detectors or home security systems. In addition, it can be used as a backup alarm system in case the primary alarm system fails. The device is designed to be long-lasting, cost-effective, and reliable.
