CMI-1295-1285T

Overview

The CMI-1295-1285T is a magnetic audio indicator buzzer manufactured by Same Sky. It features a 12 mm diameter form factor designed for through-hole mounting on printed circuit boards. The component operates at a rated voltage of 12 VDC and incorporates an internal driving circuit for direct interface with control logic. It produces a sound pressure level of 85 dB, providing clear audible alerts in electronic assemblies.

Feature Summary

• Integrated driving circuit enables direct connection to digital signals without external drivers
• Magnetic transducer technology ensures reliable acoustic performance
• Through-hole termination supports robust mechanical attachment to PCBs

Applications

• Electronic equipment status indication
• Alarm systems requiring audible feedback
• Consumer appliance control panels

Procurement Notes

Verify the specific suffix 'T' against the official Same Sky datasheet to confirm tape-and-reel packaging requirements. Ensure the 12 VDC rating matches the target system power supply. Confirm that the 85 dB output meets the required audibility standards for the intended enclosure environment before finalizing procurement.

Selection Notes

Select this component when a self-contained buzzer with built-in drive electronics is required to simplify schematic design. The through-hole package offers higher mechanical stability compared to surface-mount alternatives. Verify that the 12 mm diameter fits within the available panel or board space constraints.

Part Context

This part belongs to the Same Sky magnetic buzzer family, which provides various sizes and voltage ratings. The CMI series is characterized by its integrated driver capability, distinguishing it from passive buzzers that require external oscillation circuits. This specific model targets applications needing a compact, high-output audible alert solution.

Replacement Considerations

Consult the official Same Sky replacement guide for verified cross-reference part numbers. Do not substitute with passive buzzers unless an external oscillator circuit is added to the design.
