TUHC-88B-930-Q

Overview

The TUHC-88B-930-Q is a piezoelectric panel-mount buzzer from the Floyd Bell Turbo series. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 30 volts. The unit operates at a frequency of 3kHz with a sound pressure level of 103dB measured at 30V and 61cm distance. Supply current ranges from 65 to 125mA. It utilizes quick connect tabs measuring 0.250 inches (6.35mm) for termination.

Feature Summary

• Internally driven piezoelectric design for simplified integration
• Wide operating voltage range supporting 5 to 30V DC inputs
• High acoustic output capability with 103dB SPL rating
• Panel mount construction with standard quick-connect terminals

Applications

• Industrial control panel status indication
• Equipment fault alarm signaling
• Process monitoring system alerts

Procurement Notes

Verify the specific voltage and current requirements against your system design before procurement. Confirm that the 3kHz frequency aligns with audible alert standards for your application environment. Ensure the 0.250-inch quick connect tab dimensions match your wiring harness or terminal block specifications. Check for RoHS compliance if required by your manufacturing regulations.

Selection Notes

Select this component when a self-contained, high-decibel audible alarm is needed without external driver circuits. The wide voltage tolerance allows flexibility in power supply selection. Consider the physical size and panel cutout requirements during mechanical design. Compare against other Turbo series models if different voltage ranges or mounting styles are preferred.

Part Context

This part belongs to the Floyd Bell Turbo series of piezoelectric buzzers. These components are designed for reliable audible signaling in industrial and commercial environments. The series offers various voltage ratings and mounting options to suit diverse equipment needs while maintaining consistent acoustic performance standards.

Replacement Considerations

Direct substitutes may include other TUHC-88B-930-Q units from authorized distributors. Alternative models within the same series with compatible voltage ranges can be considered if pin-out and mounting dimensions remain identical. Verify acoustic output levels to ensure equivalent alert audibility.
