PB-0927PDWQ

Alarms, Buzzers, And Sirens Overview

The PB-0927PDWQ is a through-hole audio magnetic transducer manufactured by Mallory Sonalert Products Inc. It operates with a peak-to-peak signal voltage of 5V and produces a single tone at a frequency of 2731Hz. The device features a compact physical footprint measuring 9mm in diameter and 9mm in length, designed for integration into space-constrained electronic assemblies requiring audible signaling.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a continuous single-tone acoustic output via magnetic transduction technology
• Engineered for standard through-hole mounting on printed circuit boards
• Operates effectively within a low-voltage peak-to-peak signal range

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indication
• Consumer appliance audible alerts
• Industrial control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'DWQ' against the manufacturer's current datasheet to confirm lead times and packaging specifications. Ensure compatibility with existing PCB footprints and drive circuits before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, through-hole magnetic transducer is required for single-tone applications. Evaluate the 2731Hz frequency response against human hearing sensitivity requirements and ensure the 5V peak-to-peak drive capability matches the system's output stage.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Mallory Sonalert audio transducer portfolio, which provides standardized sound generation solutions. The PB series represents their line of compact magnetic transducers, distinct from piezoelectric buzzers or active alarm units, focusing on passive acoustic output generation.

Alarms, Buzzers, And Sirens Replacement Considerations

No public substitute part numbers are documented for this specific model. Cross-referencing requires matching the 9mm form factor, 2731Hz frequency, and through-hole termination style.
