PS-551DYQ

Overview

The PS-551DYQ is an industrial piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 5 to 15V and draws power at a frequency of 2800Hz. The device produces a sound pressure level of 105dB and utilizes a single pulse tone for audio indication. Physically, it features a circular design with a diameter of 54.3mm and a rectangular footprint measuring 54.3mm by 41mm. Termination is achieved via wire leads, facilitating integration into various electronic assemblies requiring audible alerts.

Feature Summary

• Industrial-grade piezoelectric construction for reliable audio signaling
• Single pulse tone operation for distinct alert identification
• High sound pressure output for effective warning in noisy environments
• Wire lead termination for straightforward circuit integration

Applications

• Industrial machinery status indicators
• Equipment fault alarm systems
• Control panel audio notifications
• Safety warning devices in manufacturing settings

Procurement Notes

Verify the specific voltage tolerance and current consumption requirements against the official Mallory Sonalert datasheet before integration. Confirm that the wire lead configuration matches the target PCB or harness layout. Ensure the operating environment remains within the specified electrical limits to maintain performance and longevity. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a high-decibel, single-pulse audible indicator is required for industrial applications. The 5-15VDC input range offers flexibility for various low-voltage control circuits. The compact 54.3mm diameter allows for installation in panels with limited space. Consider the wire lead termination style if soldering or crimping directly to wires is preferred over screw terminals or panel mount connectors.
