Overview
The CMI-1295IC-1285T is a magnetic audio indicator buzzer manufactured by Same Sky. It features a 12 mm diameter and operates on a 12 VDC supply voltage. The device produces an 85 dB sound pressure level at a distance of 10 cm. It utilizes through-hole mounting for PCB integration and includes an internal driving circuit for simplified interface requirements.
Feature Summary
- Integrates an internal driving circuit to simplify board-level control logic
- Employs magnetic transducer technology for reliable acoustic output
- Designed for direct through-hole insertion into printed circuit boards
Applications
- Electronic equipment status indication
- Appliance operational alerts
- Industrial control panel signaling
Procurement Notes
Verify the specific suffix configuration against official manufacturer documentation to ensure compatibility with required drive voltages and acoustic specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning. Cross-reference the exact part number with current datasheets to validate manufacturing revisions and lead time availability.
Selection Notes
Select this component when a self-contained magnetic buzzer with integrated drive electronics is required for 12 VDC systems. The through-hole format supports robust mechanical attachment. Ensure the 85 dB acoustic output meets environmental noise requirements and that the 12 mm form factor fits within the designated enclosure constraints.
Part Context
This component belongs to the CMI series of magnetic buzzers from Same Sky. The series provides various voltage and size options for audio alerting applications. The IC designation indicates the inclusion of internal drive circuitry, distinguishing it from passive piezo or magnetic variants requiring external oscillators.
Replacement Considerations
Consult official substitution guides for equivalent magnetic buzzers with matching 12 VDC ratings and through-hole footprints. Verify dimensional compatibility and acoustic performance equivalence before implementing alternative components.
