AI-4228-TF-LW140-FP-R

Alarms, Buzzers, And Sirens Overview

The PUI Audio AI-4228-TF-LW140-FP-R is a piezoelectric buzzer featuring internal drive circuitry for direct DC connection. It operates at a resonant frequency of 2.8kHz with a sound pressure level of 98dBA @ 12V, 10cm. Rated voltage is 12VDC, drawing 10mA current. The unit utilizes wire leads for termination and supports flange or panel mounting. Operating temperature ranges from -30°C to 85°C.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates internal driver circuitry for simplified single-wire or dual-wire DC control without external oscillators.
• Produces high-intensity acoustic output via piezoelectric transducer technology.
• Designed for robust industrial environments with wide operating temperature tolerance.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Medical equipment alarm systems
• Automotive dashboard alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix FP-R confirms wire lead termination and flange mount configuration against official datasheets. Ensure input voltage matches the 12VDC rating to maintain specified SPL and current draw. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when internal driving capability is required to reduce board space and design complexity. The 98dBA output suits noisy industrial settings. Verify that the wire lead termination style fits the assembly constraints compared to terminal block alternatives in the same series.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the AI series of audio indicators by PUI Audio. It shares the 42mm diameter form factor common to the family but differs in termination (wire leads) and mounting method (flange). It serves as a self-contained alert solution distinct from passive buzzers requiring external drivers.

Alarms, Buzzers, And Sirens Replacement Considerations

AI-4228-TF-LW140-R offers similar electrical characteristics but may differ in physical mounting or lead configuration. Verify mechanical dimensions and termination type compatibility before substitution.
