CMS-405-158N-67

Speakers Overview

The CMS-405-158N-67 is a miniature round speaker manufactured by Same Sky. It features a 40 mm diameter and 5.6 mm depth, designed for panel mounting. The unit utilizes a neodymium magnet and a PEN cone material. It has an impedance of 8 ohms and a power rating of 1.5 W. The self-resonant frequency is 850 Hz, with a sound pressure level of 103 dBA. Solder pads serve as the termination type.

Speakers Feature Summary

• Utilizes a high-strength neodymium magnet for efficient audio output.
• Constructed with a durable PEN cone to maintain structural integrity.
• Designed for direct panel mounting applications.
• Features solder pad terminations for straightforward circuit integration.

Speakers Applications

• Consumer electronic devices requiring compact audio output
• Industrial control panels needing audible alerts
• Medical equipment with space-constrained acoustic requirements

Speakers Procurement Notes

Verify that the specific part number matches the required acoustic specifications, particularly the 103 dBA sensitivity and 850 Hz resonance. Confirm the panel mount style and solder pad termination align with the assembly process. Ensure environmental conditions meet the operational limits defined in the official datasheet before finalizing procurement.

Speakers Selection Notes

Select this component when a high-output miniature speaker is required within a 40 mm form factor. The 1.5 W power handling supports moderate drive levels. Consider the 8-ohm impedance for compatibility with standard amplifier outputs. The panel mount design simplifies enclosure integration compared to board-mount alternatives.

Speakers Part Context

This model belongs to the CMS series of miniature speakers from Same Sky, formerly CUI Devices. The series focuses on small-form-factor audio solutions. The CMS-405-158N-67 specifically targets applications demanding high sound pressure in a compact round package. It represents a standard offering in their general-purpose speaker lineup.

Speakers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 40 mm diameter, 8-ohm impedance, and 103 dBA sensitivity against competitor catalogs.
