UW-09-628-W(F)

Overview

The UW-09-628-W(F) is a piezoelectric buzzer from the AudioLarm II series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 6 to 28V. The device operates at a frequency of 2.9kHz with a sound pressure level of 70dB @ 5V measured at 61cm. Current consumption ranges from 5 to 25mA. It utilizes wire leads for termination and is designed for panel mount installation. The unit measures 1.410 inches in diameter and has a maximum installed height of 1.480 inches. Operating temperatures span from -20°C to 65°C, and it holds UL and UR approvals.

Feature Summary

• Internally driven piezoelectric driver circuitry
• Panel mount construction with top port location
• UL and UR agency approval
• IP68 rated for dust tight and waterproof protection

Applications

• Industrial alarm systems
• Equipment status indicators
• Security warning devices

Procurement Notes

Verify the specific suffix (W-F) against official datasheets to confirm the warble tone characteristic and lead configuration. Ensure the operating voltage aligns with the 6-28V DC range. Confirm that the IP68 rating meets environmental requirements for the intended installation site. Cross-reference part numbers with manufacturer documentation to avoid confusion with similar AudioLarm II variants.

Selection Notes

Select this component when a high-intensity, internally driven piezo alarm is required for panel mounting. The wide voltage range supports various DC power supplies. Consider the 70dB SPL at low voltage if long-distance audibility is not critical, or verify higher voltage performance if louder output is needed. Ensure physical dimensions fit the enclosure constraints.

Part Context

This model belongs to the Floyd Bell AudioLarm II series, which specializes in piezoelectric warning devices. The series offers various tones and voltages for industrial applications. The UW prefix typically denotes a specific form factor within their lineup. This part is distinct from the UT series and other suffix variations that may differ in tone speed or electrical characteristics.

Replacement Considerations

Direct substitutes include the UW-09-628-S(F) and UW-09-628-W(S). Verify that the alternative suffix matches the desired tone type (fast warble vs. slow warble) and voltage compatibility. Ensure the replacement maintains the same panel mount dimensions and IP68 rating for seamless integration.
