Overview
The UO-09-628-Q is a piezoelectric audio warning device from the Floyd Bell Ultra Series. It operates on a DC input voltage range of 6 to 28 VDC with a current draw of 50 mA. The unit features an internally driven circuit and produces a whoop tone at a frequency of 2.1 kHz. Designed for panel mounting, it utilizes quick connect blade terminals with 0.250-inch (6.35 mm) tabs for electrical termination.
Feature Summary
- Generates a continuous whoop tone using piezoelectric technology
- Features an internally driven indicator circuit requiring no external driver
- Designed for direct panel mounting applications
Applications
- Industrial equipment status indication
- Vehicle safety warning systems
- Appliance audible alerts
Procurement Notes
Verify that the operating voltage of the target system falls within the 6–28 VDC range to ensure proper function. Confirm that the installation site accommodates the 35.81 mm diameter panel mount footprint. Ensure the wiring harness supports 0.250-inch quick connect blades for secure termination. Check for environmental requirements regarding temperature and humidity if used in harsh conditions.
Selection Notes
Select this model when a whoop tone is required rather than a continuous or intermittent beep. Choose based on the 6–28 VDC supply availability and the need for panel mounting over PCB mounting. Consider the 50 mA current consumption for power budget calculations. Verify that the internal drive capability matches the control signal source impedance.
Part Context
This component belongs to the Floyd Bell Ultra Series of piezoelectric alarms. It shares the same physical form factor and mounting style as other models in the series but differs in acoustic output characteristics. The series is designed for general-purpose audible warnings where high volume and distinct tones are necessary for operator awareness.
Replacement Considerations
The UC-09-628-Q offers similar electrical specifications but provides an ultra-loud continuous tone instead of a whoop tone. The UO-09-628-S is identical in form and function but may differ in specific acoustic tuning or packaging details. Verify terminal compatibility and voltage ratings before substituting.
