PK-35A29W-24VQ

Alarms, buzzers and sirens all serve essential functions in our everyday lives and PK-35A29W-24VQ is no different. This device is specifically designed to alert or signal via audible tones and is most often used for vehicle body and anti-theft alarm systems or the system of fire alarm system. The PK-35A29W-24VQ is a great device for many applications since it is very versatile, reliable and effective.

Application Field:

PK-35A29W-24VQ is mainly used in automotive applications such as alarms, security systems, smoke detectors, etc. It is designed with a built-in amplifier and an external speaker providing an amazing sound volume. Since it uses a 12V DC input, it is especially useful for companies working on the development of car electronics. It is also suitable for all places, such as factories, public places, public traffic, etc., to produce audible alarm signals. With its fairly low cost, excellent quality and high reliability, the PK-35A29W-24VQ is an ideal choice for these applications.

Working Principle:

The PK-35A29W-24VQ utilizes a piezoelectric transducer, also commonly referred to as a buzzer, to generate an audible output signal. The transducer consists of two plates that are made of a piezoelectric material. When a voltage is applied to the plates they deform slightly, causing the plates to vibrate and generating sound. This sound is then amplified by the built-in amplifier and output from the external speaker.

The PK-35A29W-24VQ also contains a power amplifier and output protection diode. The amplifier amplifies the sound signal and the protection diode protects the device from any potential damage due to short spikes or higher voltages. The volume of the output sound is easily adjusted with the use of a potentiometer which is located on the board.

Since this device uses a 12V DC power input, it is highly efficient and consumes very little power. It is also CE approved, meaning it is compliant with the relevant safety, health and environmental protection standards. It is also humidity proof which makes it a suitable device for a variety of demanding applications.

In conclusion, the PK-35A29W-24VQ is an excellent choice for applications that require an audible output signal. It is highly reliable, efficient, and cost-effective. Its wide use in vehicle body and anti-theft alarms, fire alarm systems, and other applications makes the device an ideal choice for satisfying a variety of applications.
