Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific operating voltage requirements against your system's power supply rails, as the component supports a range from 3 V to 20 V DC. Confirm that the PCB layout accommodates the 40 mm x 40 mm footprint and the through-hole terminal spacing. Ensure the enclosure design allows for unobstructed sound propagation to achieve the specified 95 dBA output level.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained audio source is required without complex driver logic. The built-in circuit simplifies schematic design compared to passive buzzers. Consider the 3.3 kHz frequency for optimal audibility in noisy environments. Evaluate the thermal dissipation capabilities if operating near the upper voltage limits continuously.

Alarms, Buzzers, And Sirens Part Context

This part belongs to PUI Audio's line of piezoelectric transducers designed for reliable audio signaling. The ASX series typically includes exciter components, while the AI series focuses on active buzzer solutions. This model represents a standard industrial-grade indicator suitable for mass production environments requiring consistent acoustic performance.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 3.3 kHz resonant frequency and 40x40mm dimensions. Verify that alternative active buzzers include integrated driver circuits to maintain compatibility with existing control logic. Check pinout configurations to ensure electrical interchangeability without PCB redesign.
