CEP-1123

Overview

The CEP-1123 is an externally driven piezoelectric audio transducer manufactured by Same Sky. It features a 24 mm diameter housing with through-hole PC pin termination for panel or board mounting. The device operates within a voltage range of 3 to 28 V and draws 7 mA at the rated 12 V supply. It produces a sound pressure level of 74 dB at 12 V with a resonant frequency of 3.2 kHz. The unit is designed for industrial applications requiring reliable acoustic signaling.

Feature Summary

• Externally driven piezoelectric design with integrated feedback mechanism
• Through-hole PC pin termination for secure circuit board attachment
• Compact 24 mm diameter form factor suitable for space-constrained enclosures

Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Electronic equipment auditory alerts

Procurement Notes

Verify the specific electrical parameters against the official Same Sky datasheet prior to integration, as external drive requirements must match the transducer's impedance characteristics. Confirm that the operating voltage remains within the 3 to 28 V range to ensure optimal performance and longevity. Ensure the PCB layout accommodates the through-hole PC pin spacing and mechanical dimensions specified in the component documentation.

Selection Notes

Select this component when an externally driven solution is required rather than an internally oscillating buzzer. The 74 dB output at 12 V provides sufficient audibility for many industrial environments. Consider the 3.2 kHz frequency for distinct alert tones. The through-hole mounting style offers robust mechanical stability compared to surface-mount alternatives in high-vibration settings.

Part Context

This part belongs to the Same Sky audio indicator portfolio, specifically focusing on piezoelectric transducers. It serves as a fundamental acoustic output component for electronic systems. The manufacturer provides technical documentation detailing the electrical characteristics and mechanical drawings necessary for proper system integration and enclosure design.
