MSW5TH

Alarms, Buzzers, And Sirens Overview

The MSW5TH is an internally driven piezoelectric buzzer from the Mallory Sonalert MSW series, designed for PCB mounting. It operates within a voltage range of 2.7 V to 5.5 VDC and draws a rated current of 400 mA. The device produces a continuous tone at a frequency between 150 Hz and 4 kHz with a sound pressure level ranging from 85 dBA to 95 dBA. It features solder pin termination and has octagonal dimensions of 23 mm in length, 13 mm in height, and 23 mm in width. The unit supports an operating temperature range from -30°C to +55°C.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design eliminates external driver circuitry requirements
• Wide frequency output capability spanning 150 Hz to 4 kHz for versatile alert tones
• Octagonal form factor optimized for compact panel or board integration

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status indicators
• Medical equipment alarm systems needing compliant audio alerts
• Consumer electronics housing for internal sound signaling
• Transportation vehicle instrumentation for operator feedback

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific frequency setting and sound pressure level against your application requirements before ordering, as the MSW5TH offers a range rather than a single fixed value. Confirm that the 400 mA current draw is supported by your power supply infrastructure. Ensure the solder pin termination method aligns with your PCB assembly process. Check for any specific certification requirements such as IEC or UL compliance relevant to your target market.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is preferred over externally driven buzzers to simplify schematic design. The wide frequency range allows customization of alert character without changing hardware. Consider the 400 mA current consumption during battery-powered designs. The octagonal shape may offer space advantages over circular counterparts in tight enclosures compared to other series options.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSW series of speakers and transducers manufactured by Mallory Sonalert Products Inc. The series focuses on compact, internally driven audio devices suitable for direct PCB integration. Unlike the SC series which uses screw terminals, this model utilizes solder pins for connection. It represents the company's standard offering for general-purpose audible indication in modern electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

The MSW5EMHSP is a documented substitute within the same manufacturer line, sharing similar electrical characteristics and form factors. Verify mechanical fit and exact frequency specifications when substituting, as variations exist within the series. No other cross-manufacturer replacements are confirmed in public documentation.
