MSE28LDP2S

Alarms, Buzzers, And Sirens Overview

The MSE28LDP2S is a piezoelectric buzzer from the MSE series by Mallory Sonalert Products Inc. It features an internally driven circuit and operates on DC input within a voltage range of 7 to 14V. The device draws 50mA of supply current and produces a sound pressure level of 85dB at 7V, measured at 30cm. It emits a frequency of 3.9kHz in a fast double pulse mode with a duration of 2 pulses per second. Designed for through-hole mounting via PC pins, it measures 23.00mm x 23.00mm and functions between -40°C and +65°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix designation against official Mallory documentation to confirm electrical characteristics, as variations exist within the MSE family. Confirm that the required operating voltage aligns with the 7-14V specification for this particular part number. Ensure mechanical compatibility with through-hole PCB layouts using standard PC pin termination methods prior to procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven piezo buzzer is required for low-voltage DC applications. The 7-14V operating range distinguishes it from higher voltage counterparts in the same series. Consider the fast double pulse output pattern if specific auditory identification is necessary. Verify that the 23mm square form factor fits the designated enclosure space.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature board mount buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by small footprint dimensions suitable for dense PCB layouts. These devices utilize piezoelectric technology to generate audible alerts without requiring external oscillators due to built-in driving circuits.

Alarms, Buzzers, And Sirens Replacement Considerations

MSE28LDP3S shares similar physical dimensions but operates at a different voltage range (20-28V). Substitution requires verification of circuit compatibility with the new voltage specifications.
