MSE28LSN2

Alarms, Buzzers, And Sirens Overview

The MSE28LSN2 is a miniature board mount buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 16 to 28 VDC and draws a current of 50 mA. The device produces a medium intensity whooping tone at a frequency of 3.5 kHz, with a sound pressure level rated between 75 and 85 dBA. It features solder pin termination for through-hole installation on printed circuit boards. The physical dimensions are 23 mm in length, 23 mm in width, and 13.5 mm in height.

Alarms, Buzzers, And Sirens Feature Summary

• Generates an internal whooping alarm tone without requiring external drive circuitry.
• Designed for direct surface mounting onto printed circuit boards via solder pins.
• Operates reliably across a wide DC voltage input spectrum.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm exact acoustic output characteristics and voltage tolerances. Ensure that the solder pin configuration matches the target PCB footprint requirements. Confirm compliance with relevant environmental directives applicable to the intended deployment region before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, self-contained audible indicator is required for space-constrained designs. The integrated driver simplifies schematic design by eliminating the need for external oscillators or transistors. Evaluate the whooping tone profile against regulatory noise requirements and user perception needs for critical alert scenarios.

Alarms, Buzzers, And Sirens Part Context

This unit belongs to the MSE series of miniature buzzers from Mallory Sonalert. The series provides various acoustic outputs and mounting options for industrial and commercial applications. The MSE28LSN2 specifically addresses needs for low-profile, high-intensity signaling in densely packed electronic assemblies where board space is limited.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Mallory Sonalert cross-reference guides for verified substitutes. Direct replacements must maintain identical voltage ratings, current consumption limits, and mechanical mounting dimensions to ensure compatibility with existing PCB layouts and power supplies.
