PT-4175WQ

Overview

The PT-4175WQ is an externally driven piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 5 VDC with a current consumption of 1.5 mA. The device produces a continuous tone at a frequency of 750 Hz and achieves a sound pressure level of 87 dBA when measured at a distance of 10 cm. Physically, it features a circular design with a diameter of 44 mm and a height of 14 mm. Termination is provided via wire leads, and the unit is designed for panel mounting using a flange style.

Feature Summary

• Externally driven piezoelectric construction for reliable audio signaling
• Flange mount configuration facilitates secure panel installation
• Wire lead termination allows for direct circuit integration

Applications

• Medical device alarm systems
• Industrial equipment status indicators
• General purpose audible alerts

Procurement Notes

Verify that the application circuit provides a stable 5 VDC supply capable of delivering at least 1.5 mA to ensure proper operation. Confirm that the mounting panel accommodates a 44 mm diameter hole and allows space for the 14 mm height profile. Ensure the environment remains within the specified -20°C to +70°C operating temperature range to maintain performance integrity.

Selection Notes

Select this component when a low-voltage, high-efficiency piezoelectric indicator is required. The 5 VDC rating suits battery-powered or low-voltage logic circuits. The 87 dBA output at 10 cm provides adequate audibility for many industrial settings. Consider the flange mount requirement during mechanical design to ensure compatibility with the enclosure structure.
