SCS series

Introduced as the first model of Sonitron’s piezoceramic speakers, the SCS-series are still being used for numerous applications.

Good sound quality and limited distortion guarantee a clear reproduction of multiple tones, speech and music.  The piezo speaker has 60 % more net sound output per membrane surface than the electro-dynamic speaker in function of the average current drain and average sound pressure level.


These loudspeakers are extremely reliable, have a robust design and can be used in difficult environmental conditions and applications because of resistance of the front to water, humidity, vibrations and dust.The SCS-speaker can be mounted by soldering the SMD pads onto the PCB.

For a pin-version, the pins can be soldered onto the PCB.  Extra stability against vibration is achieved by screwing the housing onto the application.
