PT-1404

Overview

The PT-1404 is an externally driven piezoelectric transducer manufactured by Soberton Inc. It operates at a nominal voltage of 9 V with a current consumption of 3 mA. The device produces a sound pressure level of 87 dB at 9 V measured at a distance of 10 cm. Its resonant frequency is 4.8 kHz. The physical dimensions are 13.6 mm in diameter and 4.0 mm in height. It features custom wire leads for termination.

Feature Summary

• Externally driven piezoelectric design requiring external drive circuitry
• Non-washable construction suitable for standard assembly processes
• Custom wire lead termination for flexible integration

Applications

• General purpose alarm systems
• Audible status indicators
• Security device signaling

Procurement Notes

Verify the specific electrical parameters against the official Soberton Inc. datasheet before procurement. Confirm that the 9 V operating voltage and 4.8 kHz frequency align with the target application requirements. Ensure the custom wire lead configuration meets the mechanical constraints of the final assembly. Check RoHS compliance status as indicated in product documentation.

Selection Notes

Select this component when an externally driven piezo transducer is required rather than a self-oscillating buzzer. The 9 V rating dictates the necessary drive voltage supply. The 87 dB output level is suitable for environments where moderate audible alerts are needed. Consider the non-washable nature if the manufacturing process involves aqueous cleaning steps.

Part Context

This part belongs to the Soberton Inc. line of piezoelectric buzzers and sirens. It is categorized under externally driven transducers, distinguishing it from internally driven units. The PT series typically offers various voltage and acoustic output options for different industrial and commercial signaling needs.

Replacement Considerations

The PT-1404T is listed as a related variant but operates at 5 V with 80 dB output. Direct substitution requires verifying compatibility with the existing 9 V drive circuit and checking if the acoustic difference impacts system performance.
