MSE14LDT8

Alarms, Buzzers, And Sirens Overview

The MSE14LDT8 is a piezoelectric buzzer from the Mallory Sonalert MSE series, designed for board-mount applications. It operates on a DC input voltage range of 7 to 14V and draws a supply current of 50mA. The device produces an 85-95dB sound pressure level at a frequency of 3.9kHz with a slow warble operating mode. It features internal drive circuitry and utilizes through-hole PC pin termination. The unit measures 23.00mm x 23.00mm in size with a maximum installation height of 13.60mm and functions within a temperature range of -40°C to 65°C.

Alarms, Buzzers, And Sirens Feature Summary

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix against official Mallory documentation to confirm the exact acoustic waveform and electrical characteristics. Ensure the selected variant matches the required mounting style and terminal type for the target PCB layout. Confirm compliance requirements such as RoHS status prior to final procurement decisions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a continuous tone or simple pulse is insufficient and a modulated warble signal is required for user attention. Compare against other MSE variants if different sound pressure levels or pulse rates are needed. Ensure the operating voltage aligns with the system's available DC rail within the specified 7-14V window.
