MSE28LSN2S

Alarms, Buzzers, And Sirens Overview

The MSE28LSN2S is a piezoelectric buzzer from the Mallory Sonalert MSE series, designed for through-hole mounting. It operates on a DC input voltage range of 20 to 28V with a rated current of 50mA. The device produces an audible alert at a frequency of 4kHz with a sound pressure level of 85dB measured at 30cm. It features a sealed construction and generates a slow siren tone pattern. The unit measures 23.00mm x 23.00mm with a maximum height of 13.60mm.

Alarms, Buzzers, And Sirens Feature Summary

• Sealed piezoelectric construction suitable for washdown environments
• Integrated internal driver circuitry for direct connection
• Slow siren acoustic output pattern
• Through-hole PC pin termination

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Medical equipment alarm systems
• Transportation vehicle signaling
• Consumer appliance safety alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S' confirms the sealed variant and slow siren function against the official datasheet. Confirm voltage compatibility within the 20-28V DC range. Ensure mechanical dimensions fit the target PCB or panel layout. Check RoHS compliance status if required by project specifications.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a continuous slow siren warning is required rather than intermittent pulses. The sealed design is necessary for environments exposed to moisture or cleaning agents. The internal driver simplifies circuit design by eliminating external oscillators. Verify that the 85dB SPL meets regulatory noise requirements for the intended application distance.

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 utilizes piezoelectric technology for reliable audio generation. The MSE28 designation indicates a 28V nominal operating voltage class within the product family.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with MSE28LSN2 for non-sealed variants. Compare MSE28LDP2S for different pulse patterns. Verify electrical parameters match before substitution.
