MSE28MSN3S

Alarms, Buzzers, And Sirens Overview

The MSE28MSN3S is a miniature board mount piezoelectric buzzer from the Mallory Sonalert MSE series. It operates on a DC input voltage range of 16 to 28V and draws a current of 50mA. The device produces a sound pressure level of 75dBA at a frequency of 4kHz with a chirp tone pattern repeating at 7 times per second. It features through-hole PC pin termination for board mounting and measures 23mm in length, 23mm in width, and 14mm in height.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design requiring no external oscillator circuitry
• Chirp acoustic output pattern for distinct auditory alerting
• Through-hole PCB mounting configuration with solder pin terminals

Alarms, Buzzers, And Sirens Applications

• Industrial control panel status indication
• Medical equipment operational alerts
• Consumer appliance notification systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic profile and electrical ratings against the official Mallory Sonalert datasheet before integration. Confirm that the 75dBA output meets the required audibility standards for the intended installation environment. Ensure the 50mA current draw is supported by the target power supply circuitry without exceeding capacity limits.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven audio indicator is required for low-voltage DC applications. The MSE series offers a balance of size and acoustic performance suitable for space-constrained enclosures. Consider the 4kHz frequency and chirp pattern for visibility in noisy environments where continuous tones might be overlooked or cause fatigue.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by its small form factor and internal drive capability, making it a standard choice for various electronic devices requiring reliable audio signaling without complex driver circuits.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes within the MSE series include models with similar voltage and current ratings but different acoustic patterns, such as the MSE28LDP3S or MSE28MCM3. Verify mechanical dimensions and terminal compatibility before swapping to ensure proper fit on the existing printed circuit board.
