The PKM35-4A0 MOD External Drive Piezo Transducer is a compact and efficient piezoelectric sound transducer designed for audible signalling, electronic alerts, embedded systems, consumer electronics, and industrial control applications. Operating as an external drive transducer, it requires a square wave or audio signal from an external oscillator, microcontroller, or driver circuit, providing complete flexibility over tone generation and sound patterns.
With a 4kHz resonant frequency and a sound output of 80dB at 10cm, the PKM35-4A0 MOD delivers clear and reliable audio indication for alarms, status notifications, user feedback systems, and warning signals. Its low current consumption of only 1.5mA makes it ideal for battery-powered and energy-efficient electronic designs.
Designed to operate with a drive voltage range of 9Vp-p to 25Vp-p, the transducer provides dependable performance across a variety of electronic applications. The compact round housing and flexible lead wire termination simplify installation into OEM equipment, prototypes, and custom electronic projects.
The PKM35-4A0 MOD is an excellent choice for engineers, designers, and manufacturers seeking a high-quality, low-power external drive piezo transducer for PCB and embedded system applications.
