PSR-45N08A-JQ

Speakers Overview

The PSR-45N08A-JQ is a general-purpose piezoelectric speaker manufactured by Mallory Sonalert Products Inc. It features an 8-ohm impedance and a rated power of 250 mW. The device produces a sound pressure level of 88 dB with a frequency range of 400 Hz to 6 kHz. Designed for top port audio output, it utilizes a round metal mylar construction. The component supports bracket mounting and connects via wire leads, ensuring reliable performance in industrial signaling applications.

Speakers Feature Summary

• Features a robust metal mylar diaphragm construction for durability
• Provides clear audio signaling through a dedicated top port design
• Operates efficiently at standard 8-ohm impedance levels

Speakers Applications

• Industrial machinery status indicators
• Control panel audio alerts
• General-purpose audio signaling systems

Speakers Procurement Notes

Verify the specific part number suffix against official Mallory Sonalert documentation to ensure correct acoustic and electrical specifications. Confirm that the required impedance and power ratings align with the target circuit design before procurement. Cross-reference the physical dimensions and mounting style with the mechanical drawings provided in the datasheet to guarantee proper integration into the enclosure or panel assembly.

Speakers Selection Notes

Select this component when a durable, high-output speaker is required for industrial environments. The 88 dB rating ensures audibility in noisy settings, while the 250 mW power handling provides sufficient volume for warning signals. Consider the top-port configuration for optimal sound projection directionality relative to the installation surface.

Speakers Part Context

This model belongs to the Mallory Sonalert family of audio transducers, specifically designed for audible alerting. It serves as a replacement or upgrade for older speaker components in existing industrial equipment. The product line emphasizes reliability and consistent acoustic performance across various operating conditions.

Speakers Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 250 mW power rating, and 88 dB sensitivity. Verify that alternative speakers maintain the same physical footprint and mounting hole pattern to avoid mechanical modifications during installation.
