About this item

Hassle-Free Exchanges & Returns for 30 Days. · 6-Month Limited Warranty. The DBX05 Magnetic Buzzer is a compact externally driven PCB-mount transducer designed for microcontroller projects, embedded systems, alarms, consumer electronics, industrial controls, and OEM electronic equipment. Operating from a nominal 5V DC supply with a 3V to 8V operating range, this magnetic buzzer delivers a clear 85dB sound output at 10cm when driven by an external signal. Designed for 1/2 duty cycle operation, the DBX05 requires an external square wave or oscillator circuit to generate sound, making it ideal for programmable applications where tone frequency and duration are controlled by a microcontroller or driver circuit. Its 2400Hz resonant frequency provides efficient sound generation with excellent acoustic performance. The buzzer features a compact 12mm round housing with a height of 9mm and 6.5mm pin spacing, making it easy to install directly onto printed circuit boards. Constructed with a durable Noryl housing, it offers excellent mechanical strength and reliable operation across a wide operating temperature range of -40 C to +85 C. The DBX05 is an excellent choice for battery-powered devices, embedded electronics, industrial equipment, instrumentation, and educational projects requiring an externally driven magnetic buzzer.
