    Piezo Sounder Achieves Higher Sound Pressure in Same Footprint

    08/10/2021

    Murata Electronics has newly developed the PKMCS0909E48H0-R1 SMD Piezo Sounder at 4.8 KHz which is a new and improved model from the current SMD sounder (PKMCS0909E4000-R1).The new sounder uses the same 9mm x 9mm footprint, is 1mm taller, uses new materials, operates at 800 Hz higher in frequency and boosts the sound pressure level to 75dB (+/- 2.5V0-p 4.8 kHz , square wave , 10cm). This allows for a greater sound pressure level which was previously only available in a larger size, non SMD sounder.

    Targeted applications include consumer, commercial and industrial applications where audible feedback or alarm notification is required for the operator, such as:

    • Home White Goods/Kitchen Appliances
    • Point Of Sale Electronic Registers
    • Healthcare Equipment
    • EDP equipment
    • Industrial Controls/Instrumentation

    Additional Specs:

    • SPL: 75dB typ. (+/-2.5V0-p, 4.8kHz, square wave, 10cm
    • Size: 9mm (same footprint as previous PKMCS0909E4000-R1 model)
    • Height: t=3.0mm (1.1mm higher than PKMCS0909E4000-R1)
