CPE-750P

Alarms, Buzzers, And Sirens Overview

The CPE-750P is a piezoelectric audio indicator buzzer manufactured by Same Sky. It features an internally driven design requiring a DC voltage input of 12 V. The unit operates at a frequency of 3.6 kHz and produces a sound pressure level of 80 dB when measured at 12 V. It draws a current of 7 mA during operation. The component is designed for panel mounting using PC pins and has a circular shape with a diameter of 36.5 mm and a height of 23.5 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric mechanism for simplified circuit integration
• Panel mount construction utilizing PC pin termination
• Circular housing design suitable for standard enclosure cutouts

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Consumer appliance audible alerts
• Medical device signaling systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix P indicates the PC pin variant, as other suffixes may denote different termination styles such as wire leads. Confirm the operating voltage matches the 12 VDC requirement to ensure proper acoustic output and current draw. Check RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure panel thickness accommodates the locking mechanism associated with the PC pin installation method.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an integrated driver is preferred over passive buzzers to reduce external component count. The 3.6 kHz frequency provides distinct audibility in moderate noise environments. Consider the 36.5 mm diameter for available panel space constraints. The 80 dB output is sufficient for general warning applications but may require amplification for high-noise industrial settings.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky piezo buzzer family, formerly produced under the CUI Devices brand. The series includes various sizes and drive configurations. The CPE-750P specifically addresses applications needing a self-contained audio source without external oscillator circuits. It replaces older CUI Designs equivalents within the same product lineage.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include the CPE-750 (if termination matches) or CPE-750W for wire lead versions. Verify that replacement parts maintain the 12 VDC rating and 3.6 kHz frequency to preserve acoustic performance. Cross-reference dimensions to ensure physical compatibility with existing panel mounts.
