MSE28LDP2

Alarms, Buzzers, And Sirens Overview

The MSE28LDP2 is a miniature board mount piezoelectric buzzer from the Mallory Sonalert MSE series. It operates on a DC input voltage range of 7 to 14 volts with a current rating of 50 mA. The device produces an 85 dBA sound pressure level at a frequency of 3.9 kHz. Its acoustic output is configured as a fast double pulse tone. The unit features solder pin termination for through-hole board mounting and measures 23 mm by 23 mm by 13.6 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates internal drive circuitry for direct connection to power sources without external oscillators
• Generates a distinct fast double pulse acoustic signal for clear status indication
• Constructed with a sealed piezoelectric design suitable for washable environments

Alarms, Buzzers, And Sirens Applications

• Industrial control panel status indicators
• Appliance operational alerts
• Medical equipment audio signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix code against official Mallory Sonalert documentation to confirm the exact voltage range and acoustic pattern. Ensure the ordering part number matches the required 7-14VDC specification and fast double pulse configuration. Confirm RoHS compliance status and package type directly with the manufacturer or authorized distributors before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven buzzer is required for low-voltage DC systems. The 7-14VDC operating range distinguishes it from higher voltage variants in the MSE series. The fast double pulse mode provides a unique auditory signature compared to continuous or slow pulse tones. Verify that the 23mm square footprint fits within the available PCB real estate constraints.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature board mount buzzers manufactured by Mallory Sonalert Products Inc. The series offers various voltage ratings and acoustic patterns. The MSE28LDP2 specifically targets applications requiring lower voltage operation compared to the standard 28VDC models, while maintaining the same physical dimensions and through-hole mounting style.

Alarms, Buzzers, And Sirens Replacement Considerations

MSE14LDP2S serves as a verified substitute within the same series offering identical acoustic characteristics and form factor.
