PT-3534FPQ

Overview

The PT-3534FPQ is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates at a resonant frequency of 3.4 kHz with a tolerance of ±500 Hz. The device supports an operating voltage range of 3 to 28 VDC and draws a maximum current consumption of 9.0 mA at rated voltage. It produces a minimum sound pressure level of 105 dB at 10 cm when driven at rated voltage. The unit features tin-plated brass leading pins for connection and is housed in black PC plastic resin. It is designed for panel mounting applications.

Feature Summary

• Piezoelectric transducer technology for high-intensity acoustic output
• Integrated internal drive circuitry for direct DC operation
• Robust housing constructed from black PC plastic resin
• Tin-plated brass leading pin termination style

Applications

• Industrial control panel status indication
• Equipment fault alarm signaling
• Process monitoring audio alerts
• Safety warning systems in machinery

Procurement Notes

Verify the specific suffix FPQ against official Mallory Sonalert documentation to confirm pin configuration and housing material specifications. Ensure the input power supply remains within the 3 to 28 VDC operating range to prevent damage. Confirm that the required sound pressure level of 105 dB meets the ambient noise requirements of the installation environment. Check for compliance with relevant industrial standards if used in hazardous locations.

Selection Notes

Select this component when a high-decibel audible alert is required for DC-powered systems. The wide voltage tolerance allows flexibility in power supply design. Consider the physical dimensions and panel cutout requirements during mechanical integration. Evaluate the need for internal driving capabilities versus external driver circuits based on system complexity and cost constraints.
