Overview
The CEP-2280 is an internally driven piezoelectric audio indicator manufactured by Same Sky. It features a 32 mm diameter flange design with wire leads for panel mounting. The device operates at a rated voltage of 12 Vdc, drawing 17 mA current. It produces a sound output level of 88 dB and functions within a frequency range of 2.5 kHz to 3.15 kHz. The unit supports an operating temperature range from -20°C to +60°C.
Feature Summary
- Internally driven piezoelectric transducer
- Flange mounting style with wire leads
- Compact 32 mm circular form factor
Applications
- Industrial control panels
- Alarm systems
- Appliance status indicators
Procurement Notes
Verify the specific electrical parameters against the official datasheet before integration. Confirm that the 12 Vdc rating and 88 dB sound pressure level meet the target application requirements. Ensure the operating temperature range of -20°C to +60°C is suitable for the intended environment. Check for any recent product change notices or obsolescence alerts from the manufacturer.
Selection Notes
Select this component when an internally driven buzzer is required to simplify circuit design. The 12 Vdc rating makes it compatible with standard low-voltage power supplies. The flange mount provides secure installation in enclosures. Consider the 88 dB output level for audible alerting needs in moderate noise environments.
Part Context
This part belongs to the Same Sky audio indicator series, designed for reliable acoustic signaling. It replaces older discrete driver solutions by integrating the driving circuit directly into the transducer housing. The product line emphasizes compact dimensions and straightforward wiring for industrial and consumer electronics applications.
Replacement Considerations
Direct substitutes may include other internally driven piezo buzzers with similar 12 Vdc ratings and 32 mm diameters. Verify mechanical mounting hole patterns and terminal configurations to ensure compatibility with existing PCB or panel layouts.
