SPK-PZ94-P

Overview

The SPK-PZ94-P is a full-range piezoelectric loudspeaker manufactured by ISL Products International. It features a round design with a diameter of 94mm and a maximum seated height of 15mm. The unit operates within a frequency range of 500 Hz to 20 kHz and delivers an 82 dB sound pressure level. It utilizes fast-on terminals for connection and is rated to handle 50W according to EIA standards. The operating temperature range spans from -40°C to 105°C.

Feature Summary

• Piezoelectric technology with phenolic-treated cone for robust performance
• Non-magnetic construction suitable for sensitive environments
• Slimline profile with lightweight industrial plastic housing

Applications

• Harsh industrial environments requiring durable audio signaling
• Public address systems in commercial or transportation settings
• Alarm and notification systems where non-magnetic properties are required

Procurement Notes

Verify the specific suffix 'P' against manufacturer documentation to confirm phenolic cone material and terminal type. Ensure the 50W EIA rating aligns with your system's power handling requirements. Confirm that fast-on terminals match your wiring infrastructure. Check that the -40°C to 105°C operating range meets environmental conditions. Validate the 82 dB SPL output for your acoustic needs.

Selection Notes

Select this component when a non-magnetic, high-robustness piezoelectric speaker is required. The slim 15mm height allows for installation in space-constrained enclosures. The wide temperature tolerance supports operation in extreme climates. Consider the 82 dB output level for adequate audibility in noisy industrial areas without excessive power consumption.

Part Context

This model belongs to the PZ series of piezoelectric loudspeakers designed for durability. It replaces older magnetic designs with a non-magnetic ceramic alternative. The SPK-PZ94-P variant specifically denotes the phenolic cone construction. It serves as a rugged solution for industrial signaling where standard speakers might fail due to vibration or temperature extremes.

Replacement Considerations

Direct substitutes may include other ISL PZ-series models with similar dimensions. Verify terminal types and mounting configurations before swapping. Ensure replacement units maintain the non-magnetic requirement if applicable.
