CMI-1295-12TH

Overview

The CMI-1295-12TH is a magnetic audio indicator buzzer manufactured by Same Sky. It features a 12 mm diameter and operates at a rated voltage of 12 VDC. The device produces a sound pressure level of 85 dB at 10 cm. It has an operating frequency of approximately 2.3 kHz to 2.4 kHz and draws a current of 30 mA to 100 mA depending on the specific variant documentation. The component utilizes through-hole mounting with PC pins and includes an internal driving circuit for ease of integration.

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

• General purpose electronic equipment status indication
• Appliance control panel alerts
• Industrial control system signaling

Procurement Notes

Verify the exact electrical specifications, particularly current draw and frequency, against the official Same Sky datasheet as variations exist between similar part numbers. Confirm that the through-hole pin configuration matches the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when an internally driven solution is required to reduce microcontroller load. The 12 VDC rating suits standard logic and power rails. Consider the 85 dB output sufficient for moderate noise environments. Verify physical dimensions fit within the enclosure constraints compared to other 12 mm form factors.

Part Context

This model belongs to the Same Sky CMI series of electromagnetic buzzers. The series offers various voltage and size options. The CMI-1295-12TH specifically targets applications needing a compact, self-contained audible alert without external driver transistors or complex waveforms.

Replacement Considerations

Direct substitutes include the CMI-1295-1285T and CMI-1275-12TH from the same manufacturer. Cross-brand replacements require matching the 12 VDC rating, 12 mm diameter, through-hole package, and integrated drive circuit functionality.
