MSE28LWH2

Alarms, Buzzers, And Sirens Overview

The MSE28LWH2 is a miniature board mount piezoelectric buzzer from the MSE series by Mallory Sonalert. It operates on a DC voltage range of 7 to 14 volts with a current rating of 50 mA. The device produces a slow whooping sound at a frequency of approximately 3.5 kHz, delivering a sound pressure level between 75 and 85 dBA. It features solder pin termination for board mount installation and measures 23 mm in length and width, with a height of 13.5 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a distinctive slow whooping acoustic signal for attention-grabbing alerts
• Integrates internal drive circuitry for direct connection to power sources
• Utilizes piezoelectric technology for reliable audio indication
• Designed for surface-mount or through-hole PCB integration via solder pins

Alarms, Buzzers, And Sirens Applications

• Medical equipment alarm systems
• Industrial control panel indicators
• Consumer electronics status alerts
• Transportation system notifications

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage variant required, as the MSE series includes models rated for different input ranges such as 16-28VDC. Confirm that the slow whooping tone matches the intended alert protocol. Ensure the board layout accommodates the 23mm x 23mm footprint and 13.5mm height. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-voltage (7-14V) audible indicator with a unique whooping pattern is necessary. It is suitable for space-constrained designs requiring board mounting. Compare against other MSE variants if higher voltage operation or different acoustic modes like chirp or continuous tones are preferred. Ensure the 50mA current draw fits within the system's power budget.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature board mount buzzers manufactured by Mallory Sonalert Products Inc. The series offers various acoustic modes and voltage ratings for general-purpose audio indication. These components are widely used in applications requiring compact, reliable, and internally driven piezoelectric alarms.

Alarms, Buzzers, And Sirens Replacement Considerations

MSE28LCH2: Offers similar dimensions but provides a chirp tone instead of whooping. MSE28LDP3S: Operates at a higher voltage range (20-28V) with a different frequency. Verify voltage compatibility and acoustic signature before substitution.
