Murata PKM Series 4kHz Sounder 22mm
Murata PKM Series 4kHz sounder, 22mm, 75dB SPL. Compact piezoelectric transducer for alarms & indicators. Wide temp range.
The Murata PKM Series 4kHz Sounder is a high-performance piezoelectric transducer designed for generating a clear and audible tone in a compact 22mm diameter package. Engineered for reliability, it produces a distinctive 4kHz sound frequency, making it highly effective for use as an alert or indicator in electronic devices.
This sounder generates a sound pressure level (SPL) of 75dB at a distance of 10cm, ensuring the signal is clearly perceptible even in moderately noisy environments. Its low-profile construction, with a height of just 43mm, allows for flexible integration into space-constrained designs, from consumer electronics to industrial control panels.
Constructed with robust materials, the sounder operates reliably across a wide temperature range from -20°C to +80°C, making it suitable for applications that may experience varying environmental conditions. It features a standard capacitance of 0.012µF and is designed for easy soldering into PCB assemblies.
