PSR20N08AK

Speakers Overview

The PSR20N08AK is a general-purpose piezoelectric speaker manufactured by Mallory Sonalert Products Inc. It features an 8-ohm impedance and a rated power of 300 mW, with a maximum power handling of 500 mW. The device operates within a frequency range of 560 Hz to 7 kHz and produces a sound pressure level of 92 dB. It utilizes a neodymium iron boron magnet and includes a top port location for sound emission. The unit is housed in a round metal bracket style package.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnet for high performance
• Features a top port location for directional sound output
• Constructed with a durable metal bracket style housing

Speakers Applications

• General purpose audio indication
• Embedded system alerts
• Industrial equipment signaling

Speakers Procurement Notes

Verify the specific acoustic output requirements against the 92 dB specification at the intended operating distance. Confirm that the 8-ohm impedance matches the driving circuit's output capabilities to ensure optimal power transfer. Check for any environmental constraints regarding the operating temperature range if used in extreme conditions. Ensure the physical dimensions of the round metal bracket fit the available mounting space in the final assembly design.

Speakers Selection Notes

Select this component when a robust, high-output speaker is required for embedded applications. The 300 mW rating supports moderate volume needs without excessive power consumption. The wide frequency response allows for clear voice or tone reproduction. Consider the metal bracket construction for durability in industrial environments where standard plastic housings might fail.

Speakers Part Context

This part belongs to the PSR series of speakers from Mallory Sonalert. It is designed as a direct replacement for other general-purpose speakers requiring similar electrical characteristics. The series offers various sizes and power ratings to suit different enclosure constraints and acoustic demands.

Speakers Replacement Considerations

Check compatibility with existing mounting holes due to the specific bracket dimensions. Verify that the driving voltage can sustain the 300 mW rated power without distortion. Ensure the new unit's impedance does not overload the previous driver stage.
