CEP-1173

Overview

The CEP-1173 is a piezoelectric buzzer manufactured by Same Sky (Formerly CUI Devices). It operates at a voltage of 12 VDC with a current consumption of 7 mA. The device produces a sound pressure level of 82 dB at 12V and has a resonant frequency of 3.3 kHz. The physical dimensions include a body diameter of 32 mm and a height of 14 mm. It features an external driver circuit requirement and includes a feedback mechanism. The unit is designed for panel mounting using flange leads.

Feature Summary

External driver circuit design with integrated feedback
Panel mount construction with flange leads
Piezoelectric element for acoustic output

Applications

Alarm systems
Audible notification devices
Industrial control panels

Procurement Notes

Verify the specific operating voltage and current requirements against the system design, as the component requires an external driver circuit. Confirm that the panel mounting hole dimensions accommodate the 32 mm body diameter and 14 mm height. Ensure the application environment supports the specified acoustic output levels and frequency characteristics for effective audible signaling.

Selection Notes

Select this component when a high-volume, cost-effective piezoelectric solution is required for audible alerts. The external driver configuration allows for flexible integration with various microcontroller or logic outputs. Consider the 82 dB sound pressure level and 3.3 kHz frequency to ensure compatibility with ambient noise conditions and human hearing sensitivity in the intended deployment environment.

Part Context

This part belongs to the audio transducer category, specifically within the buzzer and alarm segment. Same Sky (formerly CUI Devices) offers a range of similar piezoelectric buzzers with varying voltages, frequencies, and form factors. The CEP series typically targets applications requiring reliable, low-power audible indication in consumer electronics and industrial equipment.
