TUHT-88B-930-Q

Overview

The TUHT-88B-930-Q is a piezoelectric panel-mount buzzer from the Turbo series by Floyd Bell Inc. It features an internally driven circuit and accepts DC input within a voltage range of 9 to 30V. The unit operates at a frequency of 3kHz with a sound pressure level of 103dB. Physical dimensions include a 33.02mm diameter and a maximum seated height of 29.97mm. Current consumption varies between 65mA and 125mA depending on operating conditions.

Feature Summary

• Internally driven piezoelectric design for simplified integration
• Wide DC voltage tolerance supporting 9V to 30V operation
• High acoustic output capability for clear audible alerts

Applications

• Industrial control panel alarm systems
• HVAC equipment status indicators
• Automotive diagnostic warning units

Procurement Notes

Verify specific current draw requirements against your power supply capacity, as specifications indicate a range of 65mA to 125mA. Confirm that the 33.02mm mounting hole dimension matches your enclosure design. Ensure the operating temperature range of -20°C to +65°C aligns with your environmental conditions before finalizing procurement.

Selection Notes

Select this component when a self-contained, high-decibel alert is required without external driver circuitry. The wide voltage range allows compatibility with various DC bus architectures. Consider the physical depth constraint of under 30mm for tight enclosure installations where standard buzzers may not fit.

Part Context

This part belongs to the Turbo series of piezoelectric buzzers manufactured by Floyd Bell Inc. These components are designed for robust industrial applications requiring reliable audible signaling. The product remains in active production status, ensuring long-term availability for ongoing manufacturing projects.

Replacement Considerations

Direct substitutes include models such as TMC-86-530-Q and TMC-86-948-Q, which share similar form factors but differ in voltage ranges. Verify that alternative parts meet the 103dB sound pressure requirement and 33.02mm mounting diameter before substitution.
