CES-20134-088PMA

Overview

The CES-20134-088PMA is a miniature enclosed rectangular speaker manufactured by Same Sky. It features a PEEK cone and a neodymium magnet for efficient sound reproduction. The unit measures 20 x 13 x 4.87 mm and operates at an impedance of 8 Ohms. It has a rated power handling capacity of 0.8 W (800 mW) and delivers a sound pressure level of 91 dBA. The resonant frequency is specified at 1.3 kHz, with a functional frequency range extending up to 20 kHz. The component utilizes wire leads with a connector for integration.

Feature Summary

• Enclosed rectangular design with top port configuration
• Constructed with a durable PEEK cone material
• Utilizes a high-efficiency neodymium magnet assembly
• Includes integrated wire leads with connector

Applications

• General purpose audio output in compact electronics
• Portable consumer devices requiring small form factor speakers
• Industrial control panels needing audible alerts
• Medical equipment with space-constrained acoustic requirements

Procurement Notes

Verify the specific suffix 'PMA' to confirm the inclusion of wire leads with connectors, as other variants may differ. Ensure the 8 Ohm impedance matches the driving circuit requirements. Confirm that the 91 dBA sound pressure level meets the application's audibility needs. Check that the 20 x 13 mm footprint fits the designated enclosure space. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this model when a pre-assembled enclosed speaker is required to simplify mechanical integration. The PEEK cone offers durability compared to standard paper cones. The 8 Ohm impedance is common for low-voltage audio circuits. Consider the 0.8 W power rating to ensure it aligns with the amplifier's output capabilities without distortion. The rectangular shape allows for efficient use of linear spaces in device housings.

Part Context

This component belongs to the Same Sky CES series of enclosed speakers. The series includes various sizes and configurations, such as surface mount and different lead types. The CES-20134 designation indicates the physical dimensions and case style. Variants within this family share similar mounting characteristics but differ in electrical parameters and termination methods.

Replacement Considerations

Direct substitutes include the CES-20134-088PM, which shares the same enclosure and electrical specifications but may lack the specific connector type. Verify dimensional compatibility and impedance matching before substitution. Other Same Sky models in the CES-20134 series should be evaluated for equivalent sound pressure levels and power handling.
