CMS-40558N-L152B

Speakers Overview

The CMS-40558N-L152B is a micro speaker manufactured by Same Sky, designed for panel mount installation. It features a round frame with a diameter of 40 mm and a depth of 5.5 mm. The unit utilizes a neodymium iron boron magnet and a PEI cone to deliver an acoustic output rated at 90 dB SPL. With an impedance of 8 ohms and a power rating of 500 mW (0.5 W), it operates within a frequency range centered around 500 Hz. The component supports wire leads with connectors and functions reliably in temperatures ranging from -30°C to +70°C.

Speakers Procurement Notes

Verify the specific manufacturer part number against official Same Sky documentation to ensure authenticity. Confirm that the connector type on the wire leads matches your system requirements. Check the operating temperature range specifications against your intended environmental conditions. Ensure the mechanical dimensions fit the designated panel cutout. Validate the impedance and power ratings align with your amplifier or driver circuit capabilities before finalizing procurement.

Speakers Selection Notes

Select this component when a compact, round-form factor speaker is required for panel-mounted installations. Consider the 8-ohm impedance and 500 mW power handling to match source equipment capabilities. Evaluate the 90 dB SPL sensitivity for adequate volume in the target application environment. Verify that the -30°C to +70°C operating range covers the expected operational temperatures. Assess the wire lead configuration for ease of connection within the assembly constraints.

Speakers Part Context

This model belongs to the Same Sky CMS series of micro speakers, which are engineered for space-constrained electronic devices. The series typically offers various frame sizes and acoustic configurations to suit different audio output needs. As a product from Same Sky, formerly CUI Devices, it reflects the company's focus on providing reliable electromechanical components for diverse industrial and consumer markets.

Speakers Replacement Considerations

Consult official Same Sky documentation for verified substitute part numbers. Cross-reference mechanical dimensions, specifically the 40 mm diameter and 5.5 mm depth, to ensure physical compatibility. Match electrical parameters such as 8-ohm impedance and 500 mW power rating. Verify that the replacement maintains similar acoustic characteristics like 90 dB SPL sensitivity.
