MSE28LPS1S

Alarms, Buzzers, And Sirens Overview

The MSE28LPS1S is a piezoelectric buzzer with an internal driver, manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 20 to 28 VDC and draws a supply current of 50 mA. The device produces a sound pressure level of 85 dB at 20 VDC measured at a distance of 30 cm. Its operating frequency is 3.9 kHz, characterized by a fast pulse tone pattern. The unit features through-hole PC pin termination for board mounting and has physical dimensions of 23.00 mm x 23.00 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driver circuit for direct connection to DC power sources without external oscillators.
• Emits a high-intensity audible alert via a fast pulse tone pattern optimized for alarm applications.
• Constructed with a robust piezoelectric element designed for reliable performance in industrial environments.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Electronic equipment fault signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S' against the official Mallory Sonalert datasheet to confirm terminal type and acoustic characteristics. Ensure the application voltage remains within the 20-28 VDC range to maintain specified SPL and current ratings. Confirm mechanical fitment for the 23x23mm footprint and through-hole pin spacing prior to integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-volume piezoelectric indicator is required for panel or board mounting. The internal driver simplifies schematic design by eliminating external drive transistors. Consider the 85 dB output level relative to ambient noise requirements and verify that the 50 mA current draw aligns with the system power budget.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature board mount buzzers from Mallory Sonalert. The series is characterized by compact 23x23mm dimensions and integrated driver electronics. It serves as a standard solution for audible notification in space-constrained electronic assemblies requiring direct DC interface capabilities.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other MSE series variants such as MSE28LDP3S for continuous tone options or MSE28LCH2 for chirp patterns. Verify that substitute parts match the 23x23mm form factor and 20-28 VDC electrical specifications before substitution.
