The DB-E38-PCB Piezo Buzzer is a high-output PCB-mount audible signalling device designed for industrial electronics, alarm systems, automation equipment, security products, medical devices, and OEM electronic applications. Operating from a nominal 12V DC supply with a wide 3V to 18V DC operating range, this self-driven piezo buzzer produces a powerful 105dB sound output at 30cm, ensuring alarms and status notifications are clearly heard even in noisy environments.
Featuring an integrated oscillator, the DB-E38-PCB generates a single-tone output at 2900Hz 500Hz without requiring an external drive circuit. This simplifies system design while providing reliable and consistent audible performance.
The buzzer is designed for PCB mounting using through-hole pin terminals, making it ideal for printed circuit board assembly in industrial controls, instrumentation, access control systems, and embedded electronic equipment. Its flame-retardant ABS housing offers enhanced durability and safety, while its wide operating and storage temperature ranges ensure dependable performance in demanding environments.
With a high sound output, low-maintenance construction, and broad operating voltage range, the DB-E38-PCB is an excellent choice for professional electronic products and DIY projects alike.
