MSE28LWH2S

Alarms, Buzzers, And Sirens Overview

The MSE28LWH2S is a miniature board mount piezoelectric buzzer from the MSE series by Mallory Sonalert. It operates on a DC voltage range of 16 to 28V with a current rating of 50mA. The device produces a medium intensity whooping sound, rated at 75-85 dBA, at a frequency of 3.5 kHz. It features solder pin termination for board mounting and measures 23 mm in length and width, with a height of approximately 13.5 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a distinctive whooping acoustic signal suitable for attention-grabbing alerts
• Integrates internal drive circuitry for direct connection to control logic
• Constructed with Valox housing meeting UL94 V-0 flammability standards
• Designed for through-hole solder pin installation on printed circuit boards

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Medical device alarm systems
• Transportation vehicle monitoring panels
• Consumer appliance fault signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm if it denotes a specialized variant such as a washable construction or specific packaging format. Confirm RoHS compliance status and operating temperature range requirements match your environmental constraints before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a distinct whooping tone is required rather than a continuous beep. Ensure the PCB layout accommodates the 23mm x 23mm footprint and 13.5mm height. Verify that the 50mA current draw is supported by the power supply rail within the 16-28V DC input range.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature board mount buzzers. The series is characterized by compact dimensions and integrated driver circuits. It serves as a standard audio indicator solution for space-constrained electronic assemblies requiring reliable visual and auditory feedback mechanisms.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with MSE28MWH2 for similar whooping characteristics but verify voltage and current tolerances. Check MSE28LCH2 for chirp alternatives. Confirm mechanical compatibility and electrical specifications before substituting.
