CMI-1210-5-95T

Overview

The CMI-1210-5-95T is an internally driven magnetic audio indicator buzzer manufactured by Same Sky. It features a through-hole mounting style with PC pins for board installation. The device operates at a nominal voltage of 5 VDC and draws a current of 35 mA. It produces a sound pressure level of 95 dB measured at 10 cm distance. The resonant frequency is specified as 2.3 kHz or 2.6 kHz in available documentation. The unit has a diameter of 12 mm and a height of 9.5 mm.

Feature Summary

• Integrates internal driving circuitry for simplified interface requirements
• Utilizes electromagnetic technology for acoustic signal generation
• Designed for through-hole PCB mounting via PC pins

Applications

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

Procurement Notes

Verify the specific resonant frequency specification, as sources indicate variations between 2.3 kHz and 2.6 kHz. Confirm the operating voltage range aligns with system design, noting some references list 3 to 7 VDC while others specify 5 VDC nominal. Ensure mechanical dimensions match the target enclosure constraints.

Selection Notes

Select this component when a high-decibel audible alert is required within a compact form factor. The integrated driver reduces external component count compared to passive buzzers. Evaluate the through-hole pin configuration against the printed circuit board layout capabilities and manufacturing processes.

Part Context

This part belongs to the CMI series of magnetic buzzers from Same Sky. The series offers various voltage ratings and acoustic outputs. This specific model targets applications needing robust audible signaling with minimal drive complexity.

Replacement Considerations

Check for direct substitutes within the Same Sky CMI family that share identical mounting dimensions and electrical characteristics. Verify compatibility with existing drive circuits if replacing with different voltage variants.
