CES-503528-28PM-67

Overview

The CES-503528-28PM-67 is a general-purpose enclosed rectangular speaker manufactured by Same Sky. It features a 50 x 35 mm form factor with an integrated enclosure and IP67 rating for environmental protection. The unit utilizes a neodymium magnet and PEI cone to deliver 2 W of power handling at an 8 Ohm impedance. Its frequency response spans from 544 Hz to 20 kHz, with a self-resonant frequency of 680 Hz. The component includes wire leads equipped with a connector for straightforward integration into audio systems requiring robust, compact sound output.

Feature Summary

• IP67 rated sealed enclosure providing dust and water resistance
• Neodymium magnet construction for efficient acoustic performance
• PEI cone material for durable diaphragm operation
• Integrated connector on wire leads for simplified assembly

Applications

• Industrial equipment requiring sealed audio indicators
• Outdoor electronic devices needing weather-resistant speakers
• Medical instrumentation with hygiene-critical enclosures
• Automotive control panels exposed to harsh environments

Procurement Notes

Verify the specific connector type included with the wire leads against your system interface requirements before procurement. Confirm that the 8 Ohm impedance matches your amplifier or driver circuit specifications to ensure optimal power transfer. Ensure the physical dimensions of the 50 x 35 mm rectangular case fit within the designated mounting space of your final product design.

Selection Notes

Select this model when an enclosed, environmentally sealed speaker is required rather than a bare transducer. The IP67 rating makes it suitable for applications where standard open-frame speakers would fail due to moisture or dust ingress. Consider the 2 W power rating and 8 Ohm load when designing the driving electronics to avoid under-driving or overloading the component.

Part Context

This component belongs to Same Sky's line of standard and custom speakers, ranging from 10 mm to 205 mm in size. Same Sky acquired CUI Devices, and this part retains its original designation while being supported by the new manufacturer. The series offers various sizes and configurations to meet diverse audio output needs across different industrial and consumer sectors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure any alternative meets the same IP67 sealing requirement, 8 Ohm impedance, and physical envelope constraints to maintain system compatibility.
