CMI-1210-92T

Overview

The CMI-1210-92T is a magnetic audio indicator buzzer manufactured by Same Sky. It features a 12 mm diameter and 9.5 mm depth, designed for through-hole mounting on printed circuit boards. The device operates at a rated voltage of 12 VDC with a current consumption of 35 mA. It produces a continuous tone at a frequency of 2.4 kHz, achieving a sound pressure level of 87 dB when measured at 10 cm distance under 12 V conditions.

Feature Summary

• Integrates an internal driving circuit for direct connection to power sources without external oscillators
• Utilizes a magnetic transducer mechanism to generate continuous acoustic tones
• Constructed for reliable through-hole PCB installation with standardized pin spacing

Applications

• Electronic equipment status indicators
• Appliance operational alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the through-hole footprint matches the target PCB design constraints. Check for RoHS compliance documentation if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a self-contained, high-output audible signal is required for 12 VDC systems. The integrated driver simplifies schematic design by eliminating the need for separate oscillator circuits. Ensure the application environment supports the specified operating temperature range and acoustic output requirements.

Part Context

This part belongs to the CMI series of magnetic buzzers from Same Sky. The series offers various voltage ratings and acoustic outputs tailored for different alerting needs. The CMI-1210-92T specifically addresses applications requiring robust 12 VDC operation with moderate-to-high volume output in a compact form factor.

Replacement Considerations

Consult official substitution lists for equivalent magnetic buzzers with matching 12 VDC ratings and similar acoustic performance. Verify mechanical dimensions and pin configurations before replacing to ensure board compatibility.
