Overview
The CEP-1136 is an externally driven piezo buzzer transducer manufactured by Same Sky. It operates at a nominal voltage of 12 V with a current consumption of 7 mA. The device produces a sound pressure level of 85 dB measured at 12 V and a distance of 30 cm. Its resonant frequency is 2.8 kHz. The unit features a round shape with panel mount capabilities and flange wire leads for termination.
Feature Summary
- Externally driven piezo technology with feedback capability
- Panel mount design with integrated flange
- Wire lead terminations for direct circuit connection
Applications
- Audio equipment alert systems
- Industrial alarm indicators
- General purpose audio signaling
Procurement Notes
Verify the specific ordering suffix to ensure correct voltage and acoustic specifications match the design requirements. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement. Ensure the external driving circuit can supply the required 7 mA current at 12 V for proper operation.
Selection Notes
Select this component when a noncontinuous tone indicator is required with high acoustic output at standard operating voltages. The externally driven nature allows for frequency modulation if needed, though it is optimized for its resonant frequency. Consider the physical dimensions and panel cutout requirements during mechanical design integration.
Part Context
This part belongs to the Same Sky CEP series of piezo buzzer transducers. These components are designed for audible indication in electronic devices. The series offers various voltage and sound pressure level options to suit different application environments and regulatory noise requirements.
Replacement Considerations
Check for exact electrical parameter matches including 12 V rating, 2.8 kHz frequency, and 85 dB SPL. Verify mechanical compatibility such as the 41.80 mm diameter and mounting style. Consult official substitution lists from Same Sky for verified equivalents.
