Advanced Acoustic Technology Corp. Magnetic Buzzers

Advanced Acoustic Technology Corp. (AATC) Magnetic Buzzers offer up to 92dBA sound pressure rating, 2000Hz to 4000Hz frequency range, and 1.5V_AC to 12V_AC voltage range. These magnetic buzzers include a silicon metal plate, magnet, coil, and yoke assembled within the plastic housing. If the buzzer contains an oscillation circuit within, then it is called a self-driven buzzer or “indicator.” If the buzzer does not have an oscillation circuit, then it is known as an externally driven buzzer or “transducer”. AATC Magnetic Buzzers are suited for applications that remain still and are in stable environments.
