The CPT-3011C-120 is an externally driven piezo buzzer transducer designed for creating audible tones. It operates with a rated voltage of 12 Vdc but can function within a range of 6 to 16 Vdc. This component delivers a minimum sound pressure level of 104 dB at 30 cm and has a rated frequency between 2,500 and 3,500 Hz. It consumes a maximum of 35 mA at its rated voltage and features a wide operating temperature range from -30 to 85°C. Due to its high output and robust operating characteristics, it is well-suited for alarm systems, user interface feedback, and other electronic requiring a clear audible alert.
