CPE-502

Alarms, Buzzers, And Sirens Overview

The CPE-502 is a piezoelectric audio transducer manufactured by Same Sky. It features a rectangular profile with dimensions of 24mm x 10mm and a depth of 25mm. The device operates at a resonant frequency of 3.3kHz and delivers a sound pressure level of 93dB when driven at 10V from a distance of 10cm. It supports a maximum voltage rating of 30V and functions in a single-tone operating mode, utilizing piezo technology for acoustic signal generation.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric technology for reliable acoustic output
• Single-tone operation mode for consistent signaling
• Rectangular form factor with defined depth constraints
