CEP-2242

Overview

The CEP-2242 is a sealed, internally driven piezoelectric buzzer manufactured by Same Sky. It operates at a nominal voltage of 12 Vdc with a current consumption of 7 mA. The device produces a sound pressure level of 77 dB at a frequency of 4.1 kHz. Designed for through-hole mounting, it features a round body with a diameter of 13.7 mm and a height of 8.1 mm. The unit utilizes a single piezo element and includes an integrated driving circuit for direct connection.

Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillator circuits
• Sealed construction provides environmental protection for the audio transducer
• Through-hole termination style ensures secure board attachment

Applications

• Electronic equipment status indication
• Appliance operational alerts
• Control panel signaling

Procurement Notes

Verify the specific datasheet version from Same Sky or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure the operating environment temperature range aligns with the component specifications. Confirm that the through-hole footprint matches the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a simple, low-current audible indicator is required for 12 V systems. The internal driver simplifies schematic design by removing the need for separate drive transistors or oscillators. Consider the 77 dB output level relative to ambient noise requirements and the physical size constraints of the enclosure.

Part Context

This part belongs to the Same Sky series of piezoelectric audio indicators. These components are designed as drop-in replacements for various legacy buzzer types in consumer electronics and industrial control applications. The product line emphasizes reliability and ease of integration into standard manufacturing processes.

Replacement Considerations

Cross-reference with other internally driven 12 V piezo buzzers having similar acoustic output and form factors. Verify pin compatibility and mounting hole spacing if substituting in existing designs.
