PK-12N40PQ

Alarms, buzzers, and sirens have been used for alerting people in a variety of applications, from warning of imminent danger to signaling business owners to open their doors for the day. The PK-12N40PQ is a vibration-resistant DC buzzer for various types of applications. It is a loudspeaker that is used for making a sound by applying an alternating electrical current of a specific frequency.

The PK-12N40PQ is a really small and light compact sounder measuring only 8.5mm x 25mm x 20.5mm so it is ideal for a wide range of applications where space is limited. It is DC operated and its maximum rated voltage is 12V DC. Its maximum rated current is 40mA and its sound output level is 115 dB, making it suitable for a variety of alarm, buzzer, or siren sounds. It is also crystal controlled and has an operating frequency range of 2800 - 3300 Hz. Lastly, it has a low power consumption and is vibration-resistant so it is suitable for industrial applications.

The PK-12N40PQ is used most commonly in household and commercial applications such as smoke alarms, burglar alarms, and doorbells. It is also used in engineering and electrical applications such as fire alarm systems, generator alarms, and entry systems. In addition, it can be used in automobile applications such as luxury car interior sound systems and car manufacturer warnings.

The PK-12N40PQ works by using an alternating electrical current of a specific frequency to create a sound. This alternating current is applied to the voice coil which is attached to the sounder. The coil vibrates, creating a sound. The higher the frequency of the electricity, the higher the pitch of the sound created. The sound is mainly affected by the voice coil, the cone of the sounder, and the cabinet size.

In conclusion, the PK-12N40PQ is a great DC operated vibration-resistant DC buzzer for a variety of applications. It is small, lightweight, and low power consumption making it suitable for a variety of limited-space applications like security systems and alarms. Its maximum rated voltage is 12V DC, its maximum rated current is 40mA, and its sound output level is 115 dB. It is crystal controlled and has an operating frequency range of 2800 - 3300 Hz. It is used for producing various types of alarm, buzzer, and siren sounds.
