Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'T' confirms the through-hole package variant. Confirm the 12 Vdc operating voltage matches the target system supply. Ensure the 105 dB output level meets regulatory noise requirements for the intended enclosure environment.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a built-in oscillator is required to reduce microcontroller load. The 50 mm size provides high acoustic output compared to smaller units. Verify that the 3.25 kHz frequency aligns with human hearing sensitivity for the application context.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezo buzzer transducer family. It differs from non-integrated transducers by including internal drive electronics. The model designation indicates a 12 Vdc rating and 105 dB performance class within the product line.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference dimensions and pinout compatibility before substituting. Verify that alternative parts support the same 12 Vdc operating voltage and include integrated drivers if MCU pin direct drive is used.
