Overview
The TUHS-88G-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 measures 1.300 inches in diameter (33.02mm) with a maximum seated height of 1.180 inches (29.97mm). It operates at a frequency of 3kHz and produces an extra loud siren tone. The housing is constructed from black NORYL N-190 plastic, rated UL 94-V0 for flame resistance.
Feature Summary
- Internally driven indicator circuitry simplifies integration by eliminating external driver requirements.
- Extra loud siren tone provides high-visibility audio alerts for critical warning applications.
- Robust construction utilizes stainless steel diaphragm and epoxy or silicone potting for durability.
Applications
- High-visibility alarm systems requiring audible warnings
- Industrial control panels needing internal drive buzzers
- Safety equipment signaling devices
Procurement Notes
Verify specific lot compliance with RoHS standards as manufacturing processes may vary. Confirm that the green color variant matches the visual requirement for the intended enclosure. Ensure the panel cutout dimensions align precisely with the 33.02mm diameter specification to guarantee proper fitment and sealing integrity during installation.
Selection Notes
Select this component when an internally driven solution is required to reduce schematic complexity. The wide operating voltage range allows compatibility with various DC power supplies. Consider the physical dimensions and mounting style if space constraints exist within the target assembly housing.
Part Context
This part belongs to the Floyd Bell Turbo series of piezoelectric buzzers. These components are designed for industrial and commercial signaling where reliability and volume are paramount. The series typically includes variants with different tones and voltage ratings, sharing common form factors for easy substitution in existing designs.
Replacement Considerations
Direct substitutes include models like TMC-86-948-Q or TMC-86-530-Q from the same manufacturer, provided voltage ranges and acoustic output meet system requirements. Verify pinout compatibility and mechanical dimensions before swapping to ensure seamless integration without redesigning the PCB or panel.
