CPE-220

Alarms, Buzzers, And Sirens Overview

The CPE-220 is an internally driven piezo audio indicator buzzer manufactured by Same Sky. It operates on a rated voltage of 12 V with a supply current of 10 mA. The device produces a single tone at a frequency of 2.7 kHz, achieving a sound pressure level of 76 dB when measured at a distance of 30 cm under 12 V conditions. It features wire leads for termination and is designed for panel mount installation using a flange.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezo technology eliminates the need for external driver circuits
• Single-tone acoustic output optimized for audible alerts
• Panel mount configuration with integrated flange for secure attachment

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring visual and audible status indicators
• Consumer appliance alarm systems
• Medical equipment safety alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the required operating voltage matches the 12 V specification to ensure proper functionality and longevity. Confirm that the mounting hole diameter accommodates the 24.00 mm flange dimension. Ensure the application environment does not exceed the operational limits defined in the official datasheet. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is preferred to simplify circuit design. The 2.7 kHz frequency provides distinct audibility against background noise. Consider the 76 dB SPL rating to ensure adequate volume for the intended installation distance. Verify that the wire lead termination style fits the available wiring infrastructure.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPE series of piezo buzzers from Same Sky. The series offers various voltage and sound pressure options. The CPE-220 specifically targets 12 V applications with moderate acoustic output requirements. It serves as a direct replacement for legacy components requiring similar electrical and mechanical specifications.

Alarms, Buzzers, And Sirens Replacement Considerations

Check pinout compatibility if replacing existing designs. Verify that the new unit's 24.00 mm diameter fits the existing panel cutout. Ensure the 8.80 mm seated height clears any surrounding enclosure constraints.
