PSR4028F08S11.5K

Speakers Overview

The PSR4028F08S11.5K is a general-purpose rectangular speaker manufactured by Mallory Sonalert Products Inc. It utilizes magnetic technology and features an 8-ohm impedance with a 1-watt power rating. The device operates within a frequency range of 390 Hz to 15 kHz, delivering a sound pressure level of 97 dB. Its physical dimensions are 40 mm x 28.5 mm x 11.5 mm, constructed from plastic material with a top port configuration.

Speakers Feature Summary

• Rectangular shape designed for compact mounting applications
• Top port configuration for directed sound output
• Plastic housing construction

Speakers Applications

• General purpose audio signaling
• Industrial equipment status indication
• Control panel audio feedback

Speakers Procurement Notes

Verify the specific part number against official Mallory Sonalert documentation to ensure compatibility with system requirements. Confirm that the 8-ohm impedance and 1-watt rating match the driving circuit specifications. Check for RoHS compliance status if environmental regulations apply to the deployment environment.

Speakers Selection Notes

Select this component when a rectangular form factor is required for space-constrained installations. Ensure the driving source can handle the 8-ohm load at the specified voltage levels. Consider the 97 dB output level relative to ambient noise conditions in the intended application area.

Speakers Part Context

This speaker belongs to the PSR series of general-purpose transducers from Mallory Sonalert. It is distinct from piezoelectric buzzers or sirens, offering continuous tone reproduction rather than pulsed alarm signals. The rectangular design differentiates it from circular disc speakers in the same product family.

Speakers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Replacement requires matching the 8-ohm impedance, 1-watt rating, and 40x28.5x11.5 mm dimensions to maintain mechanical and electrical compatibility.
