TUHCH-88G-930-Q(M)

Overview

The TUHCH-88G-930-Q(M) is a panel-mount piezoelectric buzzer from the Turbo series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 9 to 48V. The device operates at a frequency of 3kHz with a sound pressure level of 103dB @ 30V measured at a distance of 61cm. It has a maximum seated height of 29.97mm and draws between 65 and 125mA during supply.

Feature Summary

• Produces high-volume audible alerts suitable for high-visibility alarm applications
• Utilizes an internally driven indicator circuit for simplified integration
• Features a robust panel mount design for secure installation

Applications

• Industrial machinery status indicators
• High-noise environment safety alarms
• Control panel auditory feedback systems

Procurement Notes

Verify the specific suffix (M) against the manufacturer's current datasheet to confirm exact acoustic output and dimensional tolerances. Ensure the driving circuit can handle the specified current draw of up to 125mA. Confirm that the operating voltage range aligns with the system power supply before procurement.

Selection Notes

Select this component when a loud, distinct tone is required in environments with significant background noise. The internal driver simplifies PCB layout by removing the need for external oscillating circuits. Consider the physical dimensions and mounting requirements to ensure compatibility with the enclosure design.

Part Context

This part belongs to the Turbo series of buzzers, designed for durability and high sound pressure levels. It is categorized under alarms, buzzers, and sirens. The product is currently active and available in bulk packaging. It serves as a direct replacement for similar internally driven piezo buzzers requiring high decibel output.

Replacement Considerations

Direct substitutes may include other models from the same Turbo series with compatible voltage ranges. Verify that any replacement maintains the 3kHz frequency and sufficient SPL for the intended application. Check mechanical fitment to ensure the new part fits the existing panel cutout.
