Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix LWH1S against official Mallory Sonalert documentation to confirm the exact waveform and electrical characteristics. Ensure the operating voltage aligns with the 16V to 28V DC specification. Confirm RoHS compliance requirements match project standards. Check for any specific handling instructions regarding soldering temperatures for the pin terminals.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven buzzer is required for board-level mounting. The MSE series offers a balance of size and acoustic performance. Consider the 50mA current draw for power budget calculations. The sealed construction is advantageous where moisture or dust resistance is needed without additional housing.

Alarms, Buzzers, And Sirens Part Context

The MSE series represents Mallory Sonalert's line of miniature board-mount buzzers. These devices are designed for integration into electronic assemblies where space is limited. The series utilizes piezoelectric technology for reliable sound generation across a wide temperature range, serving as a standard solution for audible feedback in modern electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may differ in acoustic output, current consumption, or physical dimensions. Verify that any substitute part matches the 23mm x 23mm footprint and 14mm height constraints.
