Murata | PKB24SPCH3601-B0

Murata Electronics’ piezoelectric sound components (piezo alarms) are designed for applications requiring a highly reliable acoustic alarm or audible tone signal. Their reliability extends from the fact that they are solid state construction so they have very few moving parts.

These devices can produce either a single or multi-frequency output depending upon operating requirements. The tone is distinct due to the absence of harmonics, and gives an extremely clear, penetrating sound.

With high acoustic output versus low input power requirements, Murata sound components are ideal for a wide variety of applications, especially products powered by battery.

The PKB series are unified piezoelectric sounders which have a piezoelectric diaphragm of 3 terminals connected to a  self drive circuit. They can easily generate sound with

only a DC power supply (DC3.0-20V). Using suitably designed resonant system, this type can be used where large sound volumes are needed.

The PKB24SPCH3601-B0 is a piezo alarm, encased with internal circuitry and has a sound pressure level of 90 dB @ 10 cm at 12 V.
