PK-20A25WQ

Alarms, Buzzers, And Sirens Overview

The PK-20A25WQ is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a 12 VDC supply with an internal driver circuit, drawing 25 mA of current. The device produces a continuous tone at a frequency of 2.5 kHz with a sound pressure level of 95 dBA measured at 30 cm. Designed for panel mounting via flange, it features wire lead termination. This component belongs to the PK series and serves as a robust industrial-grade audible alert solution.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driver circuit for direct connection to power sources without external oscillators.
• Generates a continuous single-tone acoustic signal suitable for steady-state alarm applications.
• Constructed with a flange mount design allowing secure installation onto control panels or enclosures.

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment failure notification systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating and current consumption against the target application circuit requirements before integration. Confirm that the wire lead termination style matches the existing wiring infrastructure. Ensure the mechanical dimensions and flange mounting configuration are compatible with the designated panel cutout and enclosure constraints to guarantee proper physical installation.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a high-decibel continuous tone is required for critical alerts in noisy environments. The internally driven nature simplifies schematic design by eliminating the need for separate oscillator components. Consider the 12 VDC operating range and wire lead format for compatibility with standard low-voltage DC control systems and existing harness layouts.

Alarms, Buzzers, And Sirens Part Context

This component is part of the PK series from Mallory Sonalert, which specializes in piezoelectric indicators and alarms. The series offers various configurations for different voltage and sound pressure requirements. The PK-20A25WQ specifically targets applications needing a loud, constant warning signal with straightforward panel mounting capabilities using wire leads.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Mallory Sonalert documentation for cross-reference data. Verify electrical parameters such as voltage, current, and SPL if substituting with other models. Ensure mechanical mounting styles and terminal types match the existing assembly requirements.
