Alarms, Buzzers, And Sirens datasheet and documents for SCE028MD3ED5B

SCE028MD3ED5B

Alarms, Buzzers, And Sirens Overview

The SCE028MD3ED5B is an industrial-grade piezoelectric buzzer from the SCE series by Mallory Sonalert. It operates on a DC voltage range of 16 to 28V with a rated current of 40mA. The device emits a medium volume sound at a frequency of 3kHz. A key functional parameter is its 10-second delay followed by a double pulse output pattern. It features screw terminal connections and is designed for panel mounting applications.

Alarms, Buzzers, And Sirens Feature Summary

Features a built-in 10-second delay mechanism before activation
Outputs a double pulse signal pattern for distinct alerting
Utilizes internal drive circuitry for direct connection
Constructed with screw terminals for secure wiring

Alarms, Buzzers, And Sirens Applications

Industrial machinery status indication
Factory safety alarm systems
Equipment fault detection alerts
Process control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify availability through authorized distributors as stock may be limited. Confirm that the 16-28VDC operating range matches your system power supply. Ensure the enclosure allows for the required panel cutout dimensions. Check for RoHS compliance documentation if required by your project specifications. Validate that the screw terminal type fits your existing wiring harness or PCB layout requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a delayed double-pulse alert is required rather than continuous sound. Compare against SCE028XD2CTB for constant tone needs or SCE028LD3MG4B for multi-tone options. Ensure the 40mA current draw is supported by your power source. Verify that the medium volume level is sufficient for the ambient noise environment of the installation site.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of industrial audio indicators. These devices are designed for harsh environments requiring reliable acoustic signaling. The series offers various tones, volumes, and timing patterns to suit different industrial notification standards and operational requirements.
