Overview
The AT-2532-ST-R is a piezoelectric buzzer manufactured by PUI Audio, Inc. It operates at a resonant frequency of 3200 Hz and delivers a sound pressure level of 90 dBA when driven at 10 VDC. The component features through-hole mounting with PC pin termination for secure board attachment. Its physical dimensions are 24 mm in diameter and 10 mm in height, designed for compact integration into electronic assemblies requiring audible alerts.
Feature Summary
- Piezoelectric transduction technology for reliable audio signal generation
- Through-hole PC pin termination for standard PCB mounting
- Compact cylindrical form factor suitable for space-constrained designs
Applications
- Industrial control panels
- Appliance status indicators
- Security system alerts
Procurement Notes
Verify the specific ordering suffix to ensure correct voltage and acoustic specifications. Confirm that the through-hole PC pin configuration matches the target PCB footprint. Check RoHS compliance documentation if required for the final assembly. Ensure drive circuitry supports the 10 VDC operating requirement for optimal performance.
Selection Notes
Select this component when a 3200 Hz tone is required for audible feedback. The 90 dBA output provides clear alerting in moderate noise environments. The 24x10 mm size allows for easy installation on various enclosure types. Consider the through-hole mounting style if surface-mount alternatives are not feasible for the mechanical design.
Part Context
This part belongs to PUI Audio's standard piezo buzzer lineup, which includes various sizes and acoustic outputs. The AT series typically denotes through-hole mounted units. PUI Audio specializes in audio components for industrial, medical, and consumer applications, offering both standard and custom solutions based on their long-standing expertise in sound production.
Replacement Considerations
Cross-reference with other 3200 Hz piezo buzzers featuring similar 90 dBA output and 24 mm diameter. Verify that substitute parts support through-hole PC pin mounting and 10 VDC operation. Ensure dimensional compatibility with existing panel cutouts and PCB holes before substitution.
