CMI-1275-85T

Overview

The CMI-1275-85T is a magnetic audio indicator buzzer manufactured by Same Sky. It operates at a rated voltage of 5 VDC with a current draw of 30 mA. The device produces an 85 dB sound pressure level at a frequency of 3.1 kHz. It features through-hole mounting with PC pins and includes an internal driving circuit for direct drive applications.

Feature Summary

• Integrates an internal driving circuit to simplify interface requirements
• Utilizes electromagnetic technology for reliable acoustic output
• Designed for through-hole PCB mounting via PC pins

Applications

• Electronic equipment status indication
• Appliance control panel alerts
• Industrial machine signaling

Procurement Notes

Verify the specific operating voltage and acoustic specifications against the official Same Sky datasheet before integration. Confirm that the through-hole footprint matches the target PCB layout. Ensure the 5 VDC supply aligns with system power rails to prevent component damage or performance deviation.

Selection Notes

Select this component when a self-contained, internally driven buzzer is required for 5 VDC systems. The integrated driver eliminates the need for external oscillators. Consider the 85 dB output and 3.1 kHz tone for audible alert applications where moderate volume is sufficient.

Part Context

This part belongs to the Same Sky CMI series of magnetic buzzers. These components are designed as compact audio indicators for various electronic devices. The series offers options for different voltages and sound levels while maintaining standard through-hole compatibility.

Replacement Considerations

Check for compatible parts within the Same Sky CMI series that share the same 5 VDC rating and through-hole pin configuration. Verify dimensional compatibility and acoustic performance equivalence before substitution.
