UB-09-628-W(S)

Overview

The UB-09-628-W(S) is a piezoelectric audio warning device manufactured by Floyd Bell Inc. It operates on a DC voltage range of 6 to 28 volts and draws a current of 50 mA. The unit produces an ultra-loud beep tone with a sound pressure level of 93 dBA to 109 dBA at a distance of 2 feet. The center frequency is specified as 2100 Hz with a tolerance of +/- 250 Hz. The component features panel mount installation with attached wires and functions within an operating temperature range of -20°C to +65°C.

Feature Summary

• Piezoelectric transducer technology for high-intensity acoustic output
• Ultra-loud beep tone configuration optimized for audible alerts
• Panel mount design with integrated wiring for direct connection

Applications

• Industrial machinery status indication
• Vehicle safety warning systems
• Commercial appliance alarm circuits

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact tone pattern and mounting style. Ensure that the electrical supply matches the 6-28 VDC requirement and that the mechanical dimensions align with the intended panel cutout specifications before finalizing procurement orders.

Selection Notes

Select this model when a high-decibel audible alert is required in environments where visual signals are insufficient. The wide voltage input range allows compatibility with various DC power architectures. Consider the wire length and connector type if integration into existing harnesses is necessary, ensuring the physical form factor fits the available enclosure space.

Part Context

This part belongs to the Floyd Bell Ultra Series of piezoelectric alarms, designed for applications demanding high sound pressure levels. The series typically includes variants with different tones and mounting options. The UB-09-628-W(S) specifically denotes the slow beep variant with wired panel mount construction, distinguishing it from continuous or fast-tone models within the same product family.

Replacement Considerations

Direct substitutes include the UC-09-628-S for continuous tone applications and the UB-09-628-W(F) for fast beep requirements. Verify that replacement units maintain the same voltage range and decibel output ratings to ensure consistent performance in the target application.
