The DB-E268 PCB Piezo Buzzer is a compact self-driven audible signalling device designed for printed circuit board mounting in industrial equipment, alarm systems, consumer electronics, security products, and embedded electronic applications. Operating from a 12V DC power supply with a wide operating voltage range of 1.5V to 28V DC, this piezo buzzer delivers a clear single-tone output at 3.5kHz, providing reliable audible alerts and status indication.
Producing a powerful 85dB sound output at 30cm while consuming only 10mA, the DB-E268 offers excellent acoustic performance with low power consumption. Its wide operating voltage range makes it suitable for a variety of electronic designs without requiring multiple buzzer variants.
The buzzer features a 23mm round housing with a 9.8mm height and 15mm pin pitch, allowing easy installation onto standard printed circuit boards. Its self-driven design eliminates the need for an external oscillator, simplifying circuit design and reducing component count.
Built using durable piezoelectric technology, the DB-E268 provides long service life, maintenance-free operation, and dependable performance in demanding applications. It is ideal for OEM equipment, automation systems, instrumentation, medical devices, and DIY electronics.
