Overview
The CEP-1141 is a piezoelectric audio transducer buzzer manufactured by Same Sky. It features a 34.5 mm diameter and 9.2 mm height, designed for panel mounting with wire leads. The component operates at a resonant frequency of 1.1 kHz with an acoustic pressure level of 81 dB. Electrical ratings include a maximum voltage of 30 V and a current draw of 9 mA. It utilizes a piezoelectric type mechanism for sound generation.
Feature Summary
- Piezoelectric transduction technology for reliable audio indication
- Panel mount construction with integrated wire leads for simplified installation
- Industrial-grade design suitable for robust operational environments
Applications
- Industrial equipment status indicators
- Control panel audio alerts
- General purpose sound signaling devices
Procurement Notes
Verify the specific datasheet version to confirm mechanical dimensions and electrical tolerances match your design requirements. Ensure the wire lead length and termination style are compatible with your assembly process. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a compact, high-volume industrial buzzer is needed. The 34.5 mm size offers a balance between acoustic output and board space. Consider the 81 dB rating against ambient noise levels. The wire lead option eliminates the need for additional connectors. Verify that the 30 V DC rating aligns with your system power supply.
Part Context
This part belongs to the Same Sky industrial buzzer family, which provides various piezoelectric solutions for audio alerting. The CEP series focuses on cost-effective, reliable indicators for mass-produced electronics. These components are commonly used in appliances, machinery, and control systems where clear auditory feedback is essential for operation or safety warnings.
Replacement Considerations
Check for direct pin-compatible substitutes within the Same Sky CEP series. Verify that any alternative maintains the same 34.5 mm diameter and 1.1 kHz frequency. Ensure the replacement meets the 81 dB minimum requirement. Confirm identical voltage and current specifications to prevent circuit damage.
