5PCS DC 3-24V Piezo Buzzer 87dB Active Beep Speaker SFM-20B

About this item

• 【Super Compatibility】This piezo buzzer has a diameter of 23 mm, close to the size of a coin. The electronic buzzer can be used on any device from 3V to 24V. Whether it's a car alarm in the garage (12V), a children's toy train (9V), or a truck reversing radar (24V), simply plug it in to use. The distance between the two mounting holes of the piezo speaker is 30mm (1.2 inches), and it can be fixed to the control panel, dashboard, or tool wall with two small screws.
• 【Clear & Not Harsh】The electric buzzer supports producing a sound of 87 decibels, which is just the right volume. It's like being able to hear equipment alarms clearly in a noisy workshop, but not as scary as a car horn. The specially designed resonant cavity of the piezo buzzer allows sound to travel further (up to 15m), with a gentle but not sharp tone.
• 【Can Withstand Harsh Weather Conditions】Whether it's extreme cold or high temperature, this piezo buzzer can produce a stable sound. The piezo speaker is made of high-quality sealing materials, which are moisture-proof, dust-proof, and oil proof. Even if thrown into the trunk of a car in summer (at a high temperature of 70 ℃), it will not deform. In winter, it can be used immediately when stored outdoors (-30 ℃).
• 【Lower Costs】Only consumes 12mA of current at 12V voltage, with energy consumption more than 30% lower than ordinary piezo buzzer. This means that the electronic buzzer alarm can work continuously for months or even years without frequent battery replacement. This can completely reduce usage costs and is a reliable choice for smart homes, IoT devices, and portable tools.
• 【5PCS Electronic Buzzer】The piezo buzzer is lightweight and has no edges or cuts. The ultra-thin height of 11mm can eliminate collision risks. The compact piezo buzzer allows you to carry it with you and replace it at any time.
