Description:
The 12V Active Electromagnetic Buzzer is a compact PCB-mount audio indicator designed to provide reliable audible alerts in electronic circuits and embedded systems. Featuring an internal oscillator, this active buzzer produces sound automatically when a 12V DC supply is applied, eliminating the need for an external signal generator.
Its lightweight plastic housing and through-hole PCB mounting design make installation quick and convenient in a wide range of electronic applications. Operating at a resonant frequency of approximately 2048Hz with a minimum sound pressure level of 80dB at 10cm, this buzzer delivers clear and effective audio notifications for alarms, industrial control systems, security devices, consumer electronics, and DIY electronics projects.
