CPE-223

Alarms, Buzzers, And Sirens Overview

The CPE-223 is an internally driven piezo indicator manufactured by Same Sky. It operates at a rated voltage of 12 V and draws a current of 13 mA. The device produces an acoustic output of 81 dB measured at 12 V with a frequency of 3.3 kHz. It utilizes through-hole mounting with PC pin termination for secure board integration.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezo mechanism eliminates the need for external driver circuitry
• Through-hole construction with PC pins ensures stable mechanical attachment to printed circuit boards

Alarms, Buzzers, And Sirens Applications

• Panel-mounted status indicators
• Control panel audio signaling
• Equipment fault alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic rating and electrical parameters against the official Same Sky datasheet before finalizing the design. Confirm that the through-hole footprint matches the target PCB layout. Ensure the operating environment supports the specified voltage and current requirements for reliable long-term performance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained audio signal source is required without complex driving electronics. The 12 V rating suits standard logic or power supply rails. Consider the 81 dB output level relative to ambient noise conditions to ensure audibility in the intended application environment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the buzzer and audio indicator category from Same Sky, formerly known as CUI Devices. It serves as a direct replacement for legacy piezo buzzers requiring simple DC input. The product line focuses on providing reliable audio feedback solutions for industrial and consumer electronic devices.

Alarms, Buzzers, And Sirens Replacement Considerations

Check pin compatibility and acoustic output levels when substituting with other internally driven piezo buzzers. Verify that the replacement part meets the same 12 V operational requirements and physical mounting constraints.
