50mm Piezoelectric Element Buzzer with Cable

The 50mm Piezoelectric Element Buzzer is a high-quality acoustic component designed for tone generation, sound signaling, or vibration sensing in electronic circuits. This bare disc buzzer features a ceramic piezo element bonded to a brass diaphragm and includes pre-soldered wire leads for easy integration.

This passive buzzer requires an external oscillating signal (such as PWM) to produce sound, giving you full control over tone frequency and output. It’s ideal for DIY electronics, educational kits, Arduino projects, and sensor experiments.
