PT-723BQ

Overview

The PT-723BQ is a piezoelectric buzzer and sound indicator manufactured by Mallory Sonalert Products Inc. It operates on an input voltage range of 5 to 30 Vpp with a resonant frequency of 2.6 kHz, specified within a tolerance of ±500 Hz. The device delivers a sound pressure level of 90 dB at the rated voltage. Designed for industrial applications, it features a chassis-mount configuration suitable for integration into control panels or equipment enclosures requiring reliable acoustic signaling.

Feature Summary

• Piezoelectric technology for consistent acoustic output
• Internal driver circuitry for direct connection capability
• Chassis mounting design for secure installation

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment fault signaling

Procurement Notes

Verify the specific ordering suffix against the official Mallory Sonalert datasheet to ensure correct voltage and acoustic specifications. Confirm that the chassis-mount style matches the enclosure requirements. Check RoHS compliance documentation if environmental regulations apply to the deployment environment. Ensure the operating voltage aligns with the system power supply before procurement.

Selection Notes

Select this component when a high-intensity 90 dB alert is required in a chassis-mounted application. The 2.6 kHz frequency provides distinct audibility. Verify that the 5-30 Vpp input range matches the available control signals. Consider the physical dimensions and mounting hole patterns to ensure compatibility with the target panel cutout.
