CES-39209-28PM

Overview

The CES-39209-28PM is a rectangular miniature loudspeaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 2 W, with a maximum power handling of 3 W. The frequency response spans from 960 Hz to 20 kHz, with a self-resonant frequency of 1200 Hz. It delivers a sound pressure level of 97 dBA when tested at 1W/1M. The unit utilizes a Nd-Fe-B magnet and a fabric cone, measuring 39.00 mm in length, 20.00 mm in width, and 9.30 mm in height. It employs wire lead termination and includes an integrated enclosure for panel mounting.

Feature Summary

• Integrated enclosed design facilitates direct panel mounting applications
• High sensitivity output achieved through neodymium iron boron magnetic structure
• Fabric diaphragm construction supports reliable acoustic performance

Applications

• Medical equipment audio indicators
• Portable electronic device alerts
• Industrial control panel signaling

Procurement Notes

Verify the manufacturer designation as Same Sky (formerly CUI Devices) during sourcing. Confirm RoHS3 compliance status and ensure the specific model suffix matches the required impedance and power ratings. Cross-reference datasheet revisions to guarantee compatibility with existing enclosure designs and mounting requirements.

Selection Notes

Select this component for applications requiring high sound pressure levels within a compact rectangular footprint. The 8 Ohm impedance suits standard amplifier outputs. Consider the included enclosure for simplified mechanical integration compared to open-frame alternatives. Ensure the frequency range aligns with the target signal bandwidth requirements.

Part Context

This speaker belongs to the CDS series of miniature rectangular transducers. It represents a specialized variant designed for enclosed panel-mount configurations. The product line emphasizes compact dimensions while maintaining robust acoustic output for general-purpose audio signaling tasks in constrained spaces.

Replacement Considerations

Direct substitutes include other Same Sky enclosed rectangular speakers with matching 8 Ohm impedance and similar dimensions. Verify that alternative models maintain the 97 dBA sensitivity rating and compatible mounting hole patterns to ensure seamless integration without redesigning the host chassis.
