CMI-1271-85-SMT-TR

Overview

The CMI-1271-85-SMT-TR is a surface-mount magnetic audio indicator buzzer manufactured by Same Sky. It operates at a nominal voltage of 12 VDC with a current rating of 30 mA. The device produces an acoustic output of 85 dB measured at a distance of 10 cm. Its operating frequency is specified as 2.4 kHz. The component features an internal driving circuit, simplifying integration into electronic designs. Physical dimensions are approximately 12 mm in length and width, with a height of 7.1 mm. It utilizes SMD/SMT termination types for PCB mounting.

Feature Summary

Integrates an internal driving circuit to simplify drive requirements
Utilizes magnetic transducer technology for audio indication
Designed for horizontal surface mount (SMT) PCB installation

Applications

Electronic equipment status indicators
Appliance audible alerts
Industrial control panel signaling

Procurement Notes

Verify the specific datasheet version for the CMI-1271-85-SMT-TR to confirm exact mechanical tolerances and electrical characteristics. Ensure the design accommodates the required 12 VDC supply and 30 mA current draw. Confirm that the 85 dB sound pressure level meets the application's audibility requirements at the intended measurement distance.

Selection Notes

Select this component when a self-contained magnetic buzzer with an integrated driver is required for 12 VDC systems. It is suitable for applications needing high acoustic output (85 dB) in a compact surface-mount form factor. Consider the 2.4 kHz tone frequency for distinct alert identification. Verify compatibility with standard SMT reflow processes during assembly planning.

Part Context

This part belongs to the Same Sky CMI series of magnetic audio indicators. These components are designed for board-level integration where space is limited but high volume production via SMT is desired. The series offers various voltage and decibel options to suit different alerting needs across consumer and industrial electronics.

Replacement Considerations

Cross-reference with other Same Sky CMI series parts or equivalent magnetic buzzers from other manufacturers offering 12 VDC operation, 85 dB output, and SMT packaging. Verify pinout compatibility and mechanical footprint dimensions before substitution.
