CMT-1285C-035

Alarms, Buzzers, And Sirens Overview

The CMT-1285C-035 is an externally driven magnetic transducer manufactured by Same Sky. It operates at a rated voltage of 3.5 V and draws 70 mA. The device produces a sound pressure level of 85 dB at 3.5 V with a resonant frequency of 2.048 kHz. It features through-hole PC pin termination and has physical dimensions of 12 mm in diameter and 8.5 mm in depth.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven electromagnetic design for flexible control
• Through-hole mounting via PC pins for PCB integration
• Compact cylindrical form factor suitable for space-constrained applications

Alarms, Buzzers, And Sirens Applications

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

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific operating voltage requirements against the datasheet, as external driving circuits must match the component's electrical characteristics. Confirm that the through-hole footprint aligns with the target PCB layout. Ensure the acoustic output meets the environmental noise requirements of the intended application before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an externally driven buzzer is required rather than an integrated oscillator type. The 3.5 V rating and 70 mA current draw define the necessary driver circuit capabilities. Consider the 85 dB acoustic output relative to the enclosure size and ambient noise levels to ensure audibility.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky CMT series of magnetic buzzers. These components are distinct from piezoelectric types due to their electromagnetic construction. The series offers various voltage and acoustic options for different signaling needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other Same Sky CMT series parts with matching voltage and acoustic specifications. Cross-manufacturer replacements require verifying identical electrical parameters and mechanical footprint compatibility.
