MSE28MCH2S

Alarms, Buzzers, And Sirens Overview

The MSE28MCH2S is a miniature board mount piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 16 to 28V and draws a current of 50mA. The device produces a medium chirp tone at a frequency of approximately 3.85kHz with a sound pressure level of 75dBA. It features solder pin termination for board mounting and measures 23mm x 23mm x 14mm.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric circuitry for direct connection
• Compact miniature form factor suitable for panel integration
• Chirp acoustic output pattern for distinct alerting

Alarms, Buzzers, And Sirens Applications

• Industrial control panels
• Medical equipment status indication
• Consumer appliance signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic rating against official datasheets, as distributor listings may vary between 75dBA and 85dBA specifications. Confirm the operating voltage range matches the target application requirements before procurement. Ensure the solder pin termination style is compatible with the intended PCB layout and assembly process.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven, low-profile audible indicator is required for 16-28V DC systems. The chirp tone provides a distinct auditory cue compared to continuous tones. Consider the 23mm square footprint and 14mm height for enclosure clearance constraints during the mechanical design phase.

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 integrated driver circuits, allowing for simple interface connections without external oscillators. These devices are widely used in applications requiring reliable, self-contained audio signaling within compact electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

The MSE28LCH2 is a similar MSE series unit with comparable dimensions and internal drive capabilities, though it specifies an 85dBA rating and 3.85kHz frequency. Verify acoustic output requirements when substituting.
