CPT-3084-85L100

Alarms, Buzzers, And Sirens Overview

The CPT-3084-85L100 is a piezo audio transducer buzzer manufactured by Same Sky. It features a circular design with a diameter of 30 mm and a maximum seated height of 8.60 mm. The component operates at a frequency of 4 kHz and delivers a sound pressure level of 82 dB when measured at 2.832 V from a distance of 10 cm. It has a voltage rating of 85 V and a current rating of 70 mA. The device utilizes wire leads for termination and includes custom lead wires.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric transducer design
• Integrated custom wire leads for direct connection
• Circular form factor suitable for panel or enclosure mounting

Alarms, Buzzers, And Sirens Applications

• General purpose audible alerts
• Alarm systems
• Industrial control panels

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific lead length and termination style required for your assembly, as the datasheet indicates custom wire leads. Confirm that the external driver circuit can supply the necessary 70 mA current at the operating voltage. Ensure the mounting surface accommodates the adhesive backing if applicable, and check that the 85 V rating exceeds your system's peak voltage requirements to prevent dielectric breakdown.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an externally driven piezo element with pre-attached wiring is preferred over soldered pin headers. The 30 mm diameter provides a balance between acoustic output and physical footprint. Consider the 4 kHz frequency response for applications requiring distinct, high-pitched alert tones rather than low-frequency warnings. Verify compatibility with the driving electronics regarding impedance and drive voltage levels.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPT series of piezo buzzers from Same Sky. It is designed as a standalone transducer element rather than a self-contained active buzzer, requiring an external oscillator or microcontroller signal to generate sound. The series offers various sizes and voltage ratings to suit different acoustic power needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 30 mm diameter, 85 V rating, and 4 kHz frequency. Check for equivalent wire lead configurations to avoid rewiring modifications. Components like the CPT-3084-85L100 are often cross-referenced with other generic piezo elements of similar dimensions, but electrical characteristics must be verified against the original datasheet.

Alarms, Buzzers, And Sirens FAQ

Is the CPT-3084-85L100 an active or passive buzzer?
