SMD Piezo sounder boasts louder output in a small footprint

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);
