CPE-522

Alarms, Buzzers, And Sirens Overview

The CPE-522 is a piezoelectric audio indicator buzzer manufactured by Same Sky. It features through-hole mounting with wire leads and an integrated driving circuit for direct signal input. The unit operates at a rated voltage of 12 VDC with a current draw of 10 mA. It produces a sound pressure level of 75 dB at the rated voltage and has a resonant frequency of 3.2 kHz. The housing dimensions are 24 mm in diameter and 10 mm in depth, suitable for panel or board applications within a temperature range of -30°C to +115°C.

Alarms, Buzzers, And Sirens Feature Summary

• Integrated driving circuit allows operation with simple digital signals without external oscillators.
• Piezoelectric transducer technology provides reliable acoustic output with low power consumption.
• Through-hole construction with wire leads facilitates secure mechanical attachment and electrical connection.

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible status alerts
• Medical equipment indicating operational states
• Consumer electronics needing compact audio feedback

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix codes if available, as they may denote variations in lead length or packaging. Confirm that the 12V DC rating aligns with the target system's power supply rails. Ensure the through-hole footprint matches the PCB design guidelines provided in the official datasheet. Check for RoHS compliance documentation if required by regional regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained buzzer with built-in drive capability is required. The 3.2 kHz frequency offers a distinct tone suitable for attention-grabbing alerts. Consider the 75 dB output level against ambient noise requirements. The wide operating temperature range supports use in harsh environments where standard components might fail.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky CPE series of piezoelectric buzzers. The series includes various models with different voltages, frequencies, and sound levels. The CPE-522 specifically targets applications needing a moderate volume output with a standard 12V interface. It complements other audio indicators in the portfolio designed for industrial and medical sectors.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 12V rating, 3.2 kHz frequency, and through-hole pinout. Verify that substitute parts include an internal driving circuit to maintain compatibility with existing control logic. Dimensional checks are necessary to ensure fit within the enclosure space.
