Speakers Procurement Notes

Verify the specific suffix against official documentation to confirm terminal type and port configuration. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the manufacturer part number with current datasheets to validate technical specifications prior to ordering.

Speakers Selection Notes

Select this model when a compact, water-resistant speaker is required for applications necessitating top-mounted acoustic output. The 8 Ohm impedance and spring terminals suit designs prioritizing ease of assembly. Evaluate enclosure requirements carefully, as rear cavity volume significantly impacts low-frequency performance despite the top-port orientation.

Speakers Part Context

This component belongs to the CMS series of miniature speakers designed for space-constrained applications. The series emphasizes durability through IP67 sealing and standardized dimensions. It serves as a specialized audio solution within the broader portfolio of Same Sky electronic components, targeting sectors where reliability and environmental sealing are critical operational parameters.

Speakers Replacement Considerations

Consult official substitution lists for verified alternatives. Generic replacements may differ in impedance, sensitivity, or sealing integrity. Verify mechanical fit and electrical compatibility before implementing any substitute part numbers.

Speakers FAQ

What material constitutes the speaker diaphragm?

The diaphragm is constructed from polyester (PET).

How does the top port design affect mounting?

The top port allows sound emission directly upward, requiring clearance above the unit rather than behind it.
