Alarms, Buzzers, And Sirens datasheet and documents for CMT-0904-83T

CMT-0904-83T

Alarms, Buzzers, And Sirens Overview

The CMT-0904-83T is an externally driven magnetic audio transducer manufactured by Same Sky. It features a 9 mm diameter and 4 mm depth, designed for through-hole mounting via PC pins. The component operates at a nominal voltage of 3 V with a current rating of 90 mA. It produces a sound pressure level of 83 dB at 3 V measured from 10 cm distance. The resonant frequency is specified at 2.73 kHz.

Alarms, Buzzers, And Sirens Feature Summary

Externally driven magnetic transducer design
Through-hole mounting with PC pins
Compact 9 mm diameter form factor

Alarms, Buzzers, And Sirens Applications

Audio indicators
Alert systems
Electronic device signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix '83T' to confirm the 83 dB acoustic output and 2.73 kHz resonant frequency. Ensure the external drive circuit provides the required 3 VDC and 90 mA current. Confirm through-hole compatibility with the target PCB footprint before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, low-profile buzzer is required for through-hole assembly. The 9 mm size suits space-constrained enclosures. Verify that the application can supply the necessary 3 V drive signal and that the 83 dB SPL meets the audible requirement.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky magnetic transducer family. These components are distinct from piezoelectric buzzers as they require an external oscillator or driver circuit to generate sound. They are commonly used in industrial and consumer electronics where reliable acoustic signaling is needed.

Alarms, Buzzers, And Sirens Replacement Considerations

Check datasheets for compatible substitutes offering identical 9 mm dimensions, 4 mm depth, and 83 dB SPL at 3 V. Ensure replacement parts support through-hole PC pin termination and match the 2.73 kHz resonant frequency for similar acoustic performance.
