Alarms, buzzers, and sirens are essential devices that are utilized for alerting others of a dangerous situation or possible hazard. The SCE048XD2DP3B is a piezo buzzer manufactured by Raltron Electronics Corporation which would traditionally be found in applications such as smoke or fire alarms, home alarm systems, and medical equipment. The purpose of this article is to explore the application field and working principle of the SCE048XD2DP3B, and to provide an understanding of its capabilities and features.

Application Field

The SCE048XD2DP3B is ideal for use in any system that requires alerting personnel of a potentially dangerous situation or warning of a hazardous situation. Such applications include smoke and fire alarms, home security systems, medical and lab equipment, industrial monitors, and various automotive systems. The SCE048XD2DP3B is capable of producing both a continuous and intermittent tone, allowing for more versatility in a wider range of applications. Additionally, the device is resistant to fluids, high humidity, and extreme temperatures, making it a great choice for both indoor and outdoor applications.

Working Principle

This piezo buzzer operates on the principle of piezoelectricity. Piezoelectricity is the generation of an electrical charge when mechanical stress is applied to a certain material. The SCE048XD2DP3B utilizes this principle by inducing a voltage when an oscillating current is passed through its crystal element. The sound is then produced when the generated voltage powers an electromagnet, which then produces a vibration that resonates in the attached metallic base. The frequency of the sound can be adjusted by altering the frequency of the oscillating current.

Other Features and Benefits

The SCE048XD2DP3B has a low current consumption of 30mA/1kHz while providing a sound pressure level of 85dB@10cm. Additionally, the SCE048XD2DP3B is rated at IP65, making it waterproof, dustproof, and resistant to water jets and dust. The device is also resistant to shock and vibration, meaning that it can withstand harsh environmental conditions. Finally, the SCE048XD2DP3B is RoHS compliant, ensuring that it meets all applicable standards for safety and reliability.

Conclusion

The SCE048XD2DP3B is a piezo buzzer that is capable of producing both a continuous and intermittent tone. This device is ideal for use in any system that requires alerting personnel of a dangerous situation such as home security systems, medical and lab equipment, and various automotive systems. It is resistant to fluids, high humidity, and extreme temperatures, and rated at IP65. Additionally, the SCE048XD2DP3B is RoHS compliant and has a low current consumption of 30mA/1kHz, while providing a sound pressure level of 85dB@10cm.
