TUHW-88W-930-Q(S)

Overview

The TUHW-88W-930-Q(S) is a piezoelectric buzzer from the Floyd Bell Turbo series, designed for panel mounting applications. It operates on a DC voltage range of 9 to 30 Vdc with an operating frequency of 3000±250 Hz. The device produces an extra loud slow warble tone and achieves a sound pressure level of 103 dB at 30V measured at a distance of 61 cm. It features quick connect tabs measuring 0.250 inches (6.35 mm) for electrical connection and is housed in a white casing.

Feature Summary

• Generates an extra loud slow warble tone for high-visibility alerting
• Internally driven piezoelectric design simplifies circuit integration
• Panel mount construction with quick connect tab terminals

Applications

• Industrial control panels requiring audible status indicators
• Medical equipment alarm systems
• Security system sirens and warning devices

Procurement Notes

Verify the specific suffix Q(S) corresponds to the slow warble tone variant, as other suffixes indicate different acoustic modes such as fast warble. Confirm that the 9-30 Vdc input range aligns with the target system power supply. Ensure the panel cutout dimensions accommodate the 33.02mm diameter housing and that the 0.250-inch quick connect tabs match the mating connector specifications.

Selection Notes

Select this component when a high-decibel audible alert is required within a compact panel-mounted form factor. The internally driven nature eliminates the need for external oscillators, reducing board space. Consider the 103 dB SPL rating for environments with moderate background noise. The wide voltage tolerance supports various industrial DC power standards without additional regulation components.

Part Context

This part belongs to the Floyd Bell Turbo series of piezoelectric buzzers, which are characterized by their robust construction and high output levels. The series offers multiple variants differentiated by tone type and voltage ratings, all sharing common mounting and connection interfaces for interchangeability within similar application constraints.

Replacement Considerations

Direct substitutes include TUHW-88W-930-Q(F) for fast warble tone or TUHW-V88B-930-Q(S) for similar acoustic performance. Verify that replacement parts maintain the same 3000 Hz frequency and 103 dB SPL rating to ensure consistent alert audibility.
