Overview
The PT-2130PSQ is a piezoelectric buzzer from the Mallory Sonalert PL series. It operates on an external drive signal with a rated voltage of 5.0 Vp-p and a maximum operating voltage of 30 Vp-p. The device produces a single tone at a resonant frequency of 3000 Hz, with a tolerance of ±500 Hz. It delivers a sound pressure level of 90 dB and features PC pin termination for mounting.
Feature Summary
- Generates a continuous single-tone acoustic alert using piezoelectric technology.
- Designed for external drive applications requiring peak-to-peak voltage control.
- Utilizes printed circuit board pin terminals for secure mechanical attachment.
Applications
- Industrial equipment status indication
- Control panel alarm signaling
- Electronic device audio alerts
Procurement Notes
Verify the specific datasheet version to confirm electrical characteristics, as specifications may vary by revision. Ensure the driving circuit can supply the required peak-to-peak voltage without exceeding the maximum rating. Confirm that the PC pin configuration matches the target PCB layout dimensions and hole spacing requirements before finalizing the component selection.
Selection Notes
Select this component when an externally driven piezoelectric source is preferred over self-oscillating types. The 3 kHz frequency provides a distinct audible alert suitable for noisy environments. Consider the 90 dB output level relative to the enclosure acoustics. Verify that the application circuitry can handle the specified 5.0 Vp-p rated voltage for optimal performance.
Part Context
This part belongs to the Mallory Sonalert PL series, which focuses on compact piezoelectric indicators. The manufacturer is known for industrial-grade audio solutions. The SC628 model represents a different product line with integrated oscillation capabilities, contrasting with the external drive requirement of the PT-2130PSQ.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 3 kHz frequency, 90 dB SPL, and PC pin footprint exactly.
