CEP-1126

Overview

The CEP-1126 is an externally driven piezo transducer designed for audio indication. It features wire leads for connection and a panel mount configuration with a flange. The component operates at a rated frequency of 2,800 Hz and delivers a sound pressure level of 92 dB when driven by a 10 Vp-p signal. It supports an operating voltage up to 30 Vp-p, with a current consumption of 5.2 mA at the 10 Vp-p drive level. The physical dimensions include a diameter of 29.5 mm.

Feature Summary

• Externally driven piezoelectric transducer technology
• Panel mount installation with integrated flange
• Wire lead termination style

Applications

• Audio indication systems
• Alarm circuits
• Status alert devices

Procurement Notes

Verify the specific datasheet version for the CEP-1126 to confirm electrical tolerances and mechanical mounting requirements. Ensure the driving circuit can supply the required 30 Vp-p peak-to-peak voltage without exceeding the component's limits. Confirm that the 29.5 mm diameter fits the intended panel cutout specifications before finalizing the design.

Selection Notes

Select this component when a high-intensity audible alert is required in a compact form factor. The externally driven nature allows for flexible waveform generation compared to self-excited buzzers. Consider the 92 dB output capability for environments requiring clear acoustic signaling over moderate background noise levels.

Part Context

This part belongs to the Same Sky audio indicator portfolio, specifically within the piezo transducer category. It serves as a passive acoustic element that requires external excitation signals to produce sound, distinguishing it from active buzzers that contain internal oscillation circuits.

Replacement Considerations
