PS-551DRQ

Overview

The PS-551DRQ is a piezoelectric industrial buzzer from the Mallory Sonalert PS series. It operates on a DC voltage range of 5 to 15 volts and draws 200 mA of current. The device produces a warble tone at a frequency of 2800 Hz with a sound pressure level of 105 dB. It features wire lead termination and bracket mount installation. Physical dimensions are 54 mm in diameter and 41 mm in height, with a unit weight of approximately 73.2 g.

Feature Summary

• Piezoelectric construction for reliable audio signaling
• Warble tone output for distinct alert identification
• Bracket mounting style for secure panel integration

Applications

• Industrial machinery status indication
• Process control alarm systems
• Transportation vehicle warning signals

Procurement Notes

Verify the specific suffix DRQ against official Mallory Sonalert documentation to confirm the exact voltage tolerance, tone type, and terminal configuration. Ensure the operating environment matches the component's specified electrical ratings. Confirm availability through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this model when a high-decibel warble alert is required within a low-voltage DC system. The bracket mount design suits applications where panel cutouts are not feasible or where external securing hardware is preferred over direct panel insertion.

Part Context
