AS03204MS-3-R

Overview

The AS03204MS-3-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a Mylar cone and Neodymium magnet, designed for board mount installation with solder pad termination. The unit has an impedance of 4 Ohms and a power rating of 1.5 W. Key acoustic parameters include a resonant frequency of 800 Hz and a sound pressure level of 85 dBA. It operates within a temperature range of -25°C to +60°C. The component measures 50 mm in diameter and 12 mm in depth, offering IP67 rated speaker face protection.

Feature Summary

• IP67 rated speaker face for enhanced environmental sealing
• Electromagnetic transducer design utilizing neodymium magnet technology
• Board mount configuration with solder pad electrical connections

Applications

• Industrial control panels requiring sealed audio indicators
• Medical equipment needing reliable acoustic signaling
• Outdoor electronic devices demanding high ingress protection

Procurement Notes

Verify the specific suffix designation during procurement, as variations may indicate different ratings or configurations. Confirm that the IP67 rating applies specifically to the speaker face assembly rather than the entire unit housing. Ensure compatibility with the intended mounting surface and soldering process to maintain the specified environmental seal integrity.

Selection Notes

Select this component when a compact, board-mountable speaker with high environmental resistance is required. The 4 Ohm impedance and 1.5 W power handling suit low-power industrial applications. Consider the 800 Hz resonant frequency for tone-specific alerts rather than broad-spectrum audio reproduction. Verify mechanical fitment against the 50 mm diameter constraint.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., which specializes in audio components for industrial and medical markets. The manufacturer provides standard and custom audio solutions, including transducers and indicators. This specific model represents a robust option within their lineup for applications requiring durable, sealed acoustic output.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should verify dimensional and electrical compatibility before substituting with other IP67-rated speakers from different manufacturers.
