AS07104PO-WR-R

Overview

The AS07104PO-WR-R is an electromagnetic speaker manufactured by PUI Audio, designed for frame mounting applications. It features a water-resistant cone construction with a treated paper diaphragm and a Neodymium Iron Boron (NdFeB) magnet. The device operates within a frequency range of 100 Hz to 20,000 Hz, with a self-resonant frequency of 250 Hz. Key electrical parameters include a nominal impedance of 4 Ohms and a power rating of 3 W. It delivers a sound pressure level of 86 dBA. Physical dimensions are 71 mm in length, 41 mm in width, and 25 mm in height. The unit utilizes solder lug end connections and functions reliably between -20°C and +60°C.

Feature Summary

• Water-resistant cone design utilizing treated paper material for durability in varied environments
• High-efficiency magnetic structure employing Neodymium Iron Boron (NdFeB) components
• Frame mount installation style suitable for secure chassis integration

Applications

• Audio output devices requiring environmental resistance
• Industrial control panel signaling systems
• Consumer electronics housing with limited space constraints

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required environmental ratings and mounting styles. Confirm that the solder lug termination type aligns with the target circuit board or wiring harness specifications. Cross-reference the operating temperature range limits with the intended application environment to guarantee reliable performance under thermal stress conditions.

Selection Notes

Select this component when a robust, water-resistant audio solution is required for frame-mounted installations. The 4-Ohm impedance and 3-Watt power handling make it suitable for standard low-voltage audio circuits. Consider the physical footprint of 71mm x 41mm for enclosure design. Ensure the operating temperature range of -20°C to +60°C meets the environmental demands of the final product deployment scenario.

Part Context

This model belongs to the AS series of speakers from PUI Audio, which focuses on providing reliable transducers for various electronic applications. The AS series typically includes options for different mounting styles and environmental protections. This specific variant emphasizes water resistance and frame mounting, distinguishing it from board-mount or general-purpose counterparts within the manufacturer's broader audio device portfolio.

Replacement Considerations

Direct substitutes may include other PUI Audio models with similar 4-Ohm impedance and frame-mount configurations, such as the AS07104PO-R if water resistance is not critical. Verify dimensional compatibility and terminal type before substitution.
