CPT-2475-92T

Alarms, Buzzers, And Sirens Overview

The CPT-2475-92T is an externally driven piezo buzzer transducer manufactured by Same Sky. It operates at a resonant frequency of 4 kHz and produces a sound pressure level of 92 dB when measured at a distance of 10 cm with a 10 V drive signal. The device requires a drive current of 8 mA and incorporates an internal capacitance of 0.021 µF. Designed for through-hole mounting, it features PC pins for PCB integration. The physical dimensions include a diameter of 24 mm and a height of 7.5 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric design requiring external oscillator circuitry
• High acoustic output capability with 92 dB sound pressure level
• Through-hole construction utilizing PC pin termination for secure board attachment

Alarms, Buzzers, And Sirens Applications

• General purpose audible signaling in electronic equipment
• Status indication in consumer appliances
• Alarm systems requiring distinct tone generation

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific drive requirements against your application circuit, as this component is externally driven and lacks internal oscillation. Confirm that the mechanical footprint matches your PCB layout, specifically the 24 mm diameter and 7.5 mm height constraints. Ensure the through-hole pitch aligns with your manufacturing capabilities. Cross-reference the datasheet for thermal and electrical limits to prevent damage during operation.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel audible alert is required without the complexity of active driver circuits. The 4 kHz frequency provides a sharp, attention-grabbing tone suitable for alarms. Consider the through-hole form factor if surface space is limited or if mechanical robustness during assembly is prioritized over miniaturization. Evaluate the 8 mA current draw against your power budget.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky family of audio transducers and buzzers. It serves as a passive signaling element within larger electronic assemblies. The manufacturer, formerly known as CUI Devices, produces this component as a standard off-the-shelf item for industrial and commercial applications requiring reliable acoustic feedback.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 24 mm diameter, 4 kHz resonance, and through-hole pin configuration. Verify that alternative parts support the same 92 dB @ 10V performance metric and 0.021 µF capacitance to ensure identical acoustic behavior in the final assembly.
