Alarms, buzzers, and sirens alert people to potential dangers or disturbances, such as a fire, flood, or intruder. The SCE028SD3SV1B is a cost-effective, low power, piezoelectric siren designed for applications requiring a high-frequency sound source.

Application Field

The SCE028SD3SV1B piezoelectric siren can be used for security systems and burglar alarms, as well as for industrial and fire alarms. It can also be used for warning sirens in hazardous environments and areas where there may be obstacles interfering with sound transmission. Additionally, this alarm can also be used for automotive and home automation applications.

Working Principle

The SCE028SD3SV1B’s working principle is based on the piezoelectric effect. When a voltage is applied to the siren, a mechanical stress is imposed on the ceramic material of the siren, causing it to vibrate and produce sound. With a wide operating voltage range of 1.8-24VDC, the siren is capable of producing a loud 115dB sound at a 10cm distance with only 4mA of current consumption.

The siren has a frequency range of 300-5000Hz and features a low temperature rise of 15° for maximum reliability and long-term operation. Furthermore, the device also features reverse polarity protection and is waterproof for outdoor applications. This makes it an ideal choice for security and alarm systems, as well as automotive and industrial applications.

Conclusion

The SCE028SD3SV1B piezoelectric siren is an effective, cost-efficient, and reliable solution for burglar alarm, security system, automotive, industrial, and home automation applications. With its wide operating voltage range and low current consumption, the siren can produce a loud sound at a 10cm distance. The device also features reverse polarity protection and is waterproof for outdoor use, making it an ideal choice for security and alarm systems.
