Introduction

The SCE028LA3DL1B device is a dual-tone, surface-mount, piezoelectric sounder. It produces a loud, “piezo” warning sound when an alarm or signal is triggered. The device is suitable for a wide range of applications in the industrial, automotive, marine, and medical industries. It is an ideal choice for warning systems, alarms, buzzers, and sirens.

Application Field and Working Principle

The SCE028LA3DL1B device is designed for industrial, automotive, marine, or medical applications. It is a dual-tone, surface-mount, piezoelectric sounder with two alarm tones. It produces a loud, “piezo” warning sound when an alarm or signal is triggered. The device can be triggered by either a DC voltage or an AC signal. The external components, such as a resistor and capacitor, can adjust the sound volume and tone. The two tone sounds produced by the device can be used to alert personnel in hazardous situations, such as smoke, fire, or gas leak detection. They can also be used to indicate the status of equipment, such as in process automation and machine tools. The device can be used in both indoor and outdoor applications.The device has a high SPL (Sound Pressure Level), producing a loud sound up to 97 dB (at one meter), making it audible in a large area. The device is protected from external electrostatic fields and reverse polarization surges. The operating temperature range is -40°C to +85°C, making it suitable for harsh environments.
