PK-16N04WA-24Q

Overview

The PK-16N04WA-24Q is an electromechanical audio indicator manufactured by Mallory Sonalert. It operates on a continuous tone at a frequency of 400 Hz with a sound pressure level of 85 dBA. The device is rated for a voltage range of 20 to 28 VDC and draws a current of 35 mA. It features wire lead termination and flange mount installation. The physical dimensions are 24 mm in length, 17 mm in width, and 15 mm in height.

Feature Summary

• Produces a continuous audible signal suitable for industrial equipment status indication
• Utilizes internally driven magnetic technology for reliable operation
• Designed for direct panel mounting via flange style installation

Applications

• Industrial control panels
• Equipment status signaling
• Machine audible alerts

Procurement Notes

Verify the specific part number suffix against official Mallory Sonalert documentation to confirm electrical ratings and mechanical configuration. Ensure the operating voltage aligns with the 20-28 VDC specification. Confirm that the flange mount style and wire lead termination meet the system integration requirements before procurement.

Selection Notes

Select this component when a low-profile, high-reliability audible indicator is required for industrial environments. The 400 Hz frequency provides distinct audibility. Consider the 85 dBA output level relative to ambient noise conditions. Verify that the 24V DC supply matches the specified operating range for optimal performance.

Part Context

This component belongs to the PK series of audio indicators from Mallory Sonalert. The series includes various voltage and frequency options. The PK-16N04WA-24Q specifically addresses applications requiring 24V DC operation with a standard continuous tone profile.

Replacement Considerations

The PK-16N04WA-12Q serves as a functional substitute within the same series but operates at 12 VDC. Verify voltage compatibility before substitution. Other PK series variants may offer different frequencies or sound levels.
