The DB-E948 Piezo Buzzer is a compact self-driven audible signalling device designed for alarm systems, industrial controls, security equipment, consumer electronics, automation systems, and OEM electronic applications. Operating from a nominal 12V DC supply with a wide 3V to 24V DC operating range, this piezoelectric buzzer delivers a clear single-tone output at 3500Hz, producing a minimum sound level of 85dB at 30cm for reliable audible alerts.
With a low current consumption of only 10mA, the DB-E948 offers an excellent combination of energy efficiency and dependable acoustic performance. Its integrated oscillator allows it to operate directly from a DC power source without requiring an external driver, simplifying installation and reducing circuit complexity.
The buzzer features flexible UL1095 AWG#28 lead wire termination, making it easy to install in control panels, electronic equipment, security devices, and custom projects. Its lightweight ABS housing provides excellent durability while maintaining a compact form factor suitable for applications where space is limited.
Designed for reliable operation across a wide temperature range, the DB-E948 is an ideal solution for industrial, commercial, and DIY electronic projects requiring a dependable audible indicator.
