AS04504PR-WP

Overview

The AS04504PR-WP is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features a 45 mm external diameter and a 4-ohm impedance with a nominal power rating of 5 watts. The device delivers a sound pressure level of 101 dB at 180 Hz. It offers a frequency range extending up to 20 kHz and includes an IP65 ingress protection rating for environmental resistance.

Feature Summary

• IP65 rated enclosure provides dust tightness and protection against water jets
• Electromagnetic driver design suitable for general audio applications
• Board mount installation style with standardized dimensions

Applications

• Consumer electronics enclosures requiring weather-resistant audio output
• Industrial control panels needing durable indicator speakers
• Medical equipment housings requiring sealed acoustic components

Procurement Notes

Verify the specific suffix requirements for your assembly, as packaging or termination variations may exist within the product line. Confirm that the IP65 rating aligns with your final enclosure sealing strategy, as proper mounting is critical for maintaining ingress protection standards during operation.

Selection Notes

Select this component when a robust, sealed speaker is required for environments exposing audio devices to moisture or dust. The 4-ohm impedance matches standard amplifier outputs, while the 5-watt rating supports higher volume demands compared to lower-power alternatives in the same form factor.

Part Context

This model belongs to PUI Audio's line of electromagnetic transducers designed for reliability in varied conditions. The manufacturer specializes in custom and standard audio solutions for medical, industrial, and consumer sectors, leveraging decades of experience in piezo and electromagnetic driver technologies.

Replacement Considerations

Direct substitutes must match the 45 mm diameter, 4-ohm impedance, and IP65 rating. Verify mechanical depth compatibility and terminal type before integration. Cross-reference datasheets for SPL and frequency response deviations to ensure acoustic performance consistency.
