Overview
The AW-15SBR-120 is a piezoelectric buzzer manufactured by PUI Audio, Inc., designed for high-voltage audio indication applications. It operates within a voltage range of 110 to 220 volts and features a base mount configuration with a 92mm base diameter. The component utilizes piezoelectric technology to generate audible alerts without requiring an internal oscillator circuit in this specific variant description, relying on the driving signal characteristics. It is categorized under alarms, buzzers, and sirens, suitable for industrial or commercial environments where robust acoustic signaling is required.
Feature Summary
- Piezoelectric transduction mechanism for reliable sound generation
- High voltage operation capability up to 220V
- Base mount installation style for secure attachment
Applications
- Industrial alarm systems
- Commercial warning devices
- High-voltage audio indicators
Procurement Notes
Verify the exact operating voltage requirements against your system design, as the part supports a wide range (110-220V). Confirm that the base mount dimensions align with your enclosure constraints. Check current availability status as distribution may vary. Ensure compatibility with your drive circuitry for piezoelectric buzzers.
Selection Notes
Select this model when high voltage direct drive is feasible and a broad acoustic output is needed without active electronics inside the buzzer. Consider the 92mm base size for mounting space. Evaluate if the piezoelectric nature meets your frequency response needs compared to electromagnetic alternatives.
Part Context
This component belongs to PUI Audio's lineup of alarms, buzzers, and sirens. It is distinct from their electromagnetic speakers and low-voltage piezo buzzers. The AW series typically denotes specific form factors and mounting styles within their audio indicator portfolio.
FAQ
What is the base diameter of the AW-15SBR-120?
The base diameter is 92mm.
Is this buzzer active or passive?
It is described as a piezo buzzer for 110-220V, typically implying it requires an AC signal or specific drive waveform rather than a DC voltage for simple tone generation, unlike active buzzers with built-in oscillators.
