CPE-164

Alarms, Buzzers, And Sirens Overview

The CPE-164 is a piezoelectric buzzer manufactured by Same Sky (Formerly CUI Devices). It features a round body with a diameter of 13.7 mm and a height of 7.6 mm. The component operates at a rated voltage of 10 VDC with a current consumption of 10 mA. It produces an acoustic output of 80 dB when driven at the rated voltage. The device utilizes through-hole PC pin termination for mounting on printed circuit boards. It is designed to function within an operating temperature range of -20°C to +70°C.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric transduction mechanism for audio indication
• Through-hole PCB mounting via PC pins
• External driver capability requiring no internal oscillator

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indicators
• Consumer appliance alert systems
• Medical device audible alarms

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the application circuit provides an external drive signal, as this model lacks an integrated oscillator. Confirm mechanical clearance for the 13.7 mm diameter and 7.6 mm height dimensions during PCB layout. Ensure the driving voltage does not exceed the 10 VDC rating to prevent damage. Check RoHS compliance documentation if required for specific regional regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a passive buzzer is required for cost-sensitive or space-constrained designs where the driving waveform is generated by the host microcontroller. Compare against active models if a simple DC voltage trigger is preferred without complex timing circuits. Consider the 80 dB sound pressure level to ensure adequate audibility in the target environment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezo audio transducer family, which includes various sizes and mounting styles. It serves as a passive alternative to active buzzers, offering flexibility in tone generation through variable frequency driving signals. The manufacturer provides CAD models and datasheets to support integration into electronic assemblies.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 13.7 mm diameter, 7.6 mm height, and 10 VDC/10 mA electrical ratings. Verify that replacement parts also utilize through-hole PC pins and operate within the same temperature range. Cross-reference with other passive piezo buzzers from different manufacturers ensuring identical form factor and acoustic performance.
