PSR-57F08S-YHQ

Speakers Overview

The PSR-57F08S-YHQ is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates with an impedance of 8 ohms at 800 Hz and a rated input power of 0.25 watts. The device delivers a sound pressure level of 86 dB and features a top port design. Physical dimensions are approximately 56.5 mm in length and 11.3 mm in height, packaged in bulk quantities.

Speakers Feature Summary

• Top port acoustic design for directional sound projection
• Piezoelectric transducer technology for reliable audio indication
• Compact rectangular form factor suitable for space-constrained enclosures

Speakers Applications

• Industrial control panel status indicators
• Medical equipment audio alerts
• Consumer appliance signaling systems

Speakers Procurement Notes

Verify the specific suffix YHQ against official Mallory Sonalert documentation to confirm exact acoustic and electrical tolerances. Ensure compatibility with existing mounting hardware due to the unique rectangular footprint. Confirm that the 8-ohm impedance matches the driving circuit requirements before integration into final assemblies.

Speakers Selection Notes

Select this component when a compact, high-output speaker is required for industrial or medical applications. The 86 dB output provides clear audibility in moderate noise environments. Consider the top port orientation during mechanical design to ensure unobstructed sound propagation toward the operator or user interface.

Speakers Part Context

This part belongs to the PSR series of piezoelectric speakers from Mallory Sonalert. It serves as a replacement for the obsolete PSR-57F08S02-JQ model. The series is designed for general-purpose audio indication where reliability and consistent performance are critical across various environmental conditions.

Speakers Replacement Considerations

Officially replaces the obsolete part number PSR-57F08S02-JQ. Verify mechanical fitment and electrical impedance matching when transitioning from the previous model to ensure seamless integration without circuit modification.
