CES-303206-240L40-67

Overview

The CES-303206-240L40-67 is a miniature rectangular loudspeaker manufactured by Same Sky. It features a neodymium magnet and a PEN cone, delivering 2W of power handling with a 4-ohm impedance. The unit operates within a frequency range of 1.28 kHz to 20 kHz, with a resonant frequency of approximately 1.6 kHz. It produces a sound pressure level of 101 dB and includes an IP67 rating for environmental protection. Dimensions are 30mm x 20mm x 6.1mm, terminating in wire leads with a connector.

Feature Summary

• IP67 rated enclosure for dust and water resistance
• Neodymium magnet construction for high efficiency
• PEN cone diaphragm material
• Rectangular form factor with integrated connector

Applications

• Industrial equipment audio alerts
• Medical device signaling
• Consumer electronics speakers
• Automotive interior audio

Procurement Notes

Verify the specific connector type and wire length requirements against your assembly drawings before ordering. Confirm that the IP67 rating meets the environmental exposure standards of your final product application. Ensure the driving circuit can supply sufficient current for the 4-ohm impedance load without distortion.

Selection Notes

Select this component when a compact, sealed speaker is required for harsh environments. The 2W power rating suits low-to-moderate volume applications. Consider the rectangular shape for space-constrained PCB or panel layouts where circular speakers do not fit efficiently.

Part Context

This model belongs to Same Sky's line of general-purpose enclosed speakers. It replaces older CUI Devices models under the same naming convention. The series offers various impedance and power options for different audio driver capabilities.

Replacement Considerations

Check mechanical footprint compatibility if substituting other rectangular speakers. Verify electrical parameters such as impedance and sensitivity match the existing amplifier design to maintain performance levels.
