CPT-3016C-120

Alarms, Buzzers, And Sirens Overview

The CPT-3016C-120 is an externally driven piezoelectric audio transducer manufactured by Same Sky. It features a 30.6 mm diameter housing with through-hole PC pin termination for PCB mounting. The device operates at a rated voltage of 12 Vdc and draws a current of 20 mA. It produces a sound pressure level of 100 dB when driven at the rated voltage from a distance of 10 cm. The resonant frequency is specified at 3.4 kHz, providing a distinct audible alert tone suitable for electronic signaling applications.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric design requiring external oscillator circuitry
• High acoustic output capability for clear audible alerts
• Through-hole mounting configuration for secure PCB integration

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems
• Industrial control panel indicators
• Consumer appliance status signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the application circuit provides an external drive signal, as this component lacks internal oscillation. Confirm mechanical fit within the enclosure for the 30.6 mm diameter and ensure the PCB layout accommodates the through-hole pin spacing. Check that the driving voltage does not exceed the 12 Vdc rating to prevent damage.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when high volume sound output is required in space-constrained designs. It is suitable for applications needing a specific tonal alert at 3.4 kHz. Ensure the host system can supply the necessary drive current and voltage without exceeding component limits.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Same Sky piezo audio transducer family, formerly associated with CUI Devices. It represents a standard through-hole buzzer solution designed for reliable acoustic signaling in various electronic devices where external drive signals are available.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other 12 V, 100 dB, 3.4 kHz externally driven piezo buzzers. Verify matching dimensions, pin pitch, and electrical ratings before substitution.
