PB-0940PW-03Q

Alarms, Buzzers, And Sirens Overview

The PB-0940PW-03Q is an externally driven magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 2 to 4 volts peak-to-peak, drawing a current of 100mA. The device generates a continuous tone at a frequency of 4kHz with a sound pressure level of 85dB measured at 10cm from the surface. This component is designed for applications requiring compact audible signaling within low-voltage systems.

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the driving circuit can supply the required 100mA current at 2-4VPP without exceeding voltage limits. Confirm mechanical mounting requirements align with the specific application enclosure. Ensure the operating environment does not exceed the thermal ratings specified in the official datasheet. Cross-reference part numbers carefully as Mallory provides cross-references for obsolete components.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a low-profile, externally driven solution is required for 3V systems. Compare against piezoelectric alternatives if higher volume or different drive voltages are needed. Consider the 85dB output level relative to ambient noise conditions. Evaluate the physical dimensions against available space constraints in the target assembly.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Sonalert brand lineup of audible warning devices. Mallory Sonalert specializes in industrial, medical, and consumer audio indicators. The PB series represents magnetic buzzer technologies distinct from their piezoelectric line. These devices are widely used in sectors requiring reliable, standardized audible feedback mechanisms.

Alarms, Buzzers, And Sirens Replacement Considerations

Mallory Sonalert maintains cross-reference sheets for obsolete Murata buzzers. Verify compatibility with existing Murata equivalents if replacing legacy designs. Check for updated manufacturing revisions that may affect pinout or acoustic performance.
