CMS-3646-18S

Speakers Overview

The CMS-3646-18S is a round general-purpose speaker manufactured by Same Sky. It features a 36 mm diameter frame with a depth of 4.6 mm. The unit utilizes a Neodymium (NdFeB) magnet and a PET diaphragm material. Electrical specifications include an 8 Ohm impedance, a 1 Watt power rating, and a resonant frequency of 500 Hz. The device employs spring contacts for termination and is designed for panel mount installation.

Speakers Feature Summary

• Utilizes a high-strength Neodymium magnet for efficient acoustic output
• Constructed with a durable PET diaphragm for consistent performance
• Features spring contact terminations for simplified circuit integration

Speakers Applications

• General purpose audio indication
• Panel mounted sound alerts
• Consumer electronics audio output

Speakers Procurement Notes

Verify the specific termination style upon ordering. Confirm that the receiving equipment supports spring contact interfaces rather than wire leads or solder tabs. Ensure mechanical clearance accommodates the 36 mm diameter and 4.6 mm depth dimensions. Validate electrical compatibility with the 8 Ohm impedance and 1 Watt power handling capabilities before finalizing the design.

Speakers Selection Notes

Select this component when a compact round speaker with spring contacts is required. Compare against models requiring wire leads if soldering is preferred. Consider the 500 Hz resonant frequency for low-frequency response limitations. Evaluate the 1 Watt power rating against system volume requirements to ensure adequate headroom without distortion.

Speakers Part Context

This model belongs to the Same Sky miniature speaker family, formerly associated with CUI Devices. It represents a standard industrial-grade transducer option. The product line emphasizes reliable acoustic performance in small form factors suitable for various electronic enclosures.

Speakers Replacement Considerations

CMS-3646-18L200 offers similar dimensions but uses wire leads instead of spring contacts. CMS-3058-18L200 provides a larger 30 mm diameter option with different acoustic characteristics. Verify interface compatibility when substituting.
