CMS-181325-078S-67

Speakers Overview

The CMS-181325-078S-67 is a rectangular, top-port general-purpose speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 700 mW, with a maximum power handling of 1 W. The device operates within a frequency range of 500 Hz to 10 kHz, exhibiting a self-resonant frequency of 800 Hz. It delivers a sound pressure level of 93 dBA at 700 mW/100mm. Constructed with a PET diaphragm and Nd-Fe-B magnet, it offers IP67 protection against dust and water ingress. The unit utilizes spring-type terminals for connection and measures 18.00 mm in length, 13.00 mm in width, and 2.50 mm in height.

Speakers Feature Summary

• IP67-rated enclosure provides comprehensive protection against dust and water ingress for reliable operation in harsh environments.
• Top port design facilitates direct acoustic coupling and efficient sound projection in compact enclosures.
• Spring-type terminal connections enable rapid and secure wiring without the need for soldering.
• Rectangular form factor with low profile dimensions supports integration into space-constrained electronic devices.

Speakers Applications

• Medical equipment requiring waterproof audio components
• Industrial control panels exposed to moisture or dust
• Consumer electronics needing robust miniature speakers
• Outdoor instrumentation with environmental sealing requirements

Speakers Procurement Notes

Verify the specific suffix 'S' confirms the spring-type terminal configuration, as other variants may utilize different connection methods. Ensure the IP67 rating aligns with your enclosure design, as full environmental protection depends on proper mounting and sealing during assembly. Confirm that the 700 mW power rating meets your application's acoustic output needs without exceeding thermal limits. Check for RoHS compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this component when a rugged, waterproof speaker is required for compact applications. The 8 Ohm impedance matches standard amplifier outputs, while the 93 dBA sensitivity ensures adequate volume. Consider the top-port orientation for optimal sound directionality. The IP67 rating makes it suitable for washdown environments or outdoor use where standard speakers would fail. Evaluate the physical dimensions against available board space.
