CEP-1114

Overview

The CEP-1114 is an externally driven piezo audio transducer buzzer manufactured by Same Sky. It features a round design with a diameter of 30 mm and a depth of 13.5 mm. The component operates at a frequency of 2 kHz and produces a sound pressure level of 93 dB when driven at 10 Vp-p. It has a voltage rating of 30 VDC and draws 11 mA of current. The device utilizes through-hole PC pin termination for mounting.

Feature Summary

• Externally driven piezoelectric construction
• Through-hole mounting configuration
• High acoustic output capability

Applications

• Industrial equipment status indication
• Consumer appliance alert systems
• Medical device signaling

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions before integration. Ensure driver circuits can supply the required peak-to-peak voltage without exceeding the DC rating. Confirm RoHS compliance documentation matches the manufacturing batch requirements for your region.

Selection Notes

Select this model for applications requiring high volume audible alerts where external driving signals are available. Compare against internal oscillator buzzers if self-contained operation is needed. Evaluate the 93 dB output against ambient noise levels to ensure adequate audibility in the target environment.

Part Context

This component belongs to the Same Sky piezo audio transducer family, formerly associated with CUI Devices. It serves as a standard industrial-grade sounder for panel mount or wire lead applications. The product line focuses on reliable acoustic signaling solutions for electronic assemblies.

Replacement Considerations

Direct substitutes may include other 30 mm piezo buzzers from manufacturers like Murata or NMB Technologies. Verify that replacement parts match the 2 kHz frequency and 93 dB SPL specifications to maintain system performance.
