PS-522Q

Overview

The PS-522Q is an industrial-grade piezoelectric audio indicator manufactured by Mallory Sonalert. It operates on a 12 VDC nominal voltage with a current rating of 200 mA. The device produces a warble tone at a frequency of 3 kHz and achieves a sound pressure level of 105 dBA. Physical dimensions are 40 mm in length, 58 mm in width, and 45 mm in height. It utilizes wire leads for termination and is designed for bracket mounting.

Feature Summary

• Generates a distinct warble acoustic signal for high-visibility alerting
• Constructed with piezoelectric technology for reliable operation
• Engineered for industrial environments with robust housing

Applications

• Industrial machinery fault signaling
• Process control panel status indication
• Automated equipment warning systems

Procurement Notes

Verify the specific voltage tolerance and environmental ratings against the official Mallory Sonalert datasheet before integration. Confirm that the bracket mounting style aligns with the mechanical design constraints of the target enclosure. Ensure the wire lead termination method matches the available connection infrastructure to prevent installation errors.

Selection Notes

Select this model when a high-decibel warble tone is required for critical alerts. The 12 VDC operating range suits standard low-voltage DC power supplies. The bracket mount configuration allows for flexible positioning without requiring panel cutouts, making it suitable for retrofitting or external mounting scenarios where space is limited.

Part Context

This component belongs to the Mallory Sonalert series of industrial audio indicators. The manufacturer specializes in piezoelectric alarms and sensors for medical, industrial, and consumer applications. The PS series typically features durable construction and high-output acoustics designed for noisy operational environments.

Replacement Considerations

Consult the official Mallory Sonalert cross-reference documentation for verified substitute part numbers. Do not assume compatibility based on similar physical dimensions or voltage ratings alone.
