AT-5535-T-R

Overview

The PUI Audio AT-5535-T-R is an electromechanical buzzer transducer designed for audible signaling applications. It operates with a minimum supply voltage of 1V AC and draws a typical operating current of 30 mA. The device delivers a peak-to-peak signal swing of 90 Vp-p, ensuring robust acoustic output. Key performance metrics include a sound pressure level (SPL) of 95 dBA at the resonant frequency of 3.5 kHz, with a minimum SPL rating of 80 dB. The unit features surface-mount technology (SMD) construction with dimensions of 2.5 mm height by 7.5 mm width and length.

Feature Summary

Electromechanical buzzer design providing reliable audible alerts
Surface-mount configuration for automated assembly integration
High sound pressure level output for clear signaling in noisy environments

Applications

Industrial control panel indicators
Consumer electronics alert systems
Medical device status signaling

Procurement Notes

Verify the specific datasheet version to confirm mechanical footprint tolerances and soldering profile requirements. Ensure the application circuit supports the 1V AC minimum supply voltage and 30 mA current draw. Confirm that the 95 dBA SPL meets the regulatory noise limits for the intended deployment environment. Cross-reference the SMD package dimensions against the PCB layout to prevent clearance issues.

Selection Notes

Select this component when a high-output audible alarm is required in a compact form factor. The 3.5 kHz resonant frequency provides distinct audibility compared to lower-frequency buzzers. Consider the 90 Vp-p drive requirement for driver circuit compatibility. This part is suitable for designs prioritizing volume and reliability over low-power consumption constraints.

Part Context

PUI Audio specializes in audio components including transducers and speakers. The AT series represents their line of electromechanical buzzers. This model is part of their standard portfolio for general-purpose signaling needs across industrial and consumer sectors.
