Active Buzzer 24V, 2.3kHz

The TMB-12A24 active buzzer is an electronic component for acoustic signaling in low-voltage DC circuits. Thanks to its built-in electronics, it generates a sound signal upon the application of a supply voltage without the need for an external oscillator. It is suitable for device status signaling, alerts, and simple sound indications on a printed circuit board (PCB).
