Overview
The UO-19-230-S is a piezoelectric buzzer from the Floyd Bell Turbo series, designed for panel mounting with a diameter of 35.81mm. It features an internally driven indicator circuit and accepts both AC and DC input types within a voltage range of 20 to 30V. The device produces a whoop tone and utilizes quick connect blades with screws for electrical connection. Packaged in bulk, this component is currently active and RoHS compliant.
Feature Summary
- Internally driven piezoelectric mechanism generating a whoop tone
- Dual compatibility with AC and DC power inputs
- Panel mount design with quick connect blade terminals
Applications
- Industrial control panel alarm systems
- Equipment status indication units
- Safety warning devices requiring audible alerts
Procurement Notes
Verify that the operating environment supports the specified 20 to 30V AC/DC input range. Confirm that the mounting hole diameter accommodates the 35.81mm form factor. Ensure the installation method aligns with the quick connect blade terminal requirements. Check for RoHS compliance documentation if required by specific regulatory standards.
Selection Notes
Select this model when an internally driven solution is preferred over externally driven buzzers. Choose based on the requirement for a whoop tone rather than a continuous beep. Consider the panel mount configuration and quick connect termination style for integration into existing wiring harnesses or terminal blocks.
Part Context
This part belongs to the Floyd Bell Turbo series of piezoelectric buzzers. It shares the internal driver architecture with other models in the line but differs in voltage rating and acoustic output characteristics. The series is characterized by robust construction suitable for industrial environments.
Replacement Considerations
Cross-reference with TMC-86-530-Q for similar panel mount dimensions but verify voltage compatibility as it operates at 5 to 30V DC. Compare with UO-19-230-Q for identical mechanical specifications while confirming voltage range alignment.
