UW-09-628-Q(F)D

Overview

The UW-09-628-Q(F)D is a piezoelectric chime alarm manufactured by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and 61 cm distance. Power consumption ranges from 5 to 25 mA depending on the applied voltage. It is designed for panel mounting with wire leads exiting from the top. The unit is rated IP68 for dust tightness and waterproofing, ensuring durability in harsh environments. Operating temperatures span from -20°C to 65°C. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm.

Feature Summary

• IP68 rated enclosure providing complete dust tightness and waterproof protection for reliable operation in wet or dusty conditions.
• Internally driven piezoelectric mechanism eliminates the need for external driver circuits, simplifying system integration.
• Top-mounted wire lead configuration facilitates straightforward electrical connections during panel installation.

Applications

• Industrial machinery status indicators requiring environmental resistance
• Marine equipment alarm systems needing waterproof components
• Outdoor control panel signaling devices

Procurement Notes

Verify that the specific suffix (F)D matches the required lead length and termination style for your assembly. Confirm the operating voltage aligns with your system's power supply to ensure correct sound pressure levels. Check UL/UR certification requirements against local safety regulations before finalizing procurement specifications.

Selection Notes

Select this component when high environmental sealing is critical alongside simple DC drive requirements. Compare the 70 dB SPL output against ambient noise levels to ensure audibility. Ensure the panel cutout accommodates the 35.81 mm diameter and verify clearance for the 37.59 mm height constraint.

Part Context

This part belongs to the AudioLarm II series of piezoelectric chimes. It shares design characteristics with other models in the lineup but is distinguished by its specific voltage range and IP68 sealing rating. The series focuses on robust, self-contained audible signaling solutions for demanding industrial applications.

Replacement Considerations

Cross-reference with other Floyd Bell models offering IP68 ratings if exact substitution is unavailable. Verify that replacement units maintain the same 2.9 kHz frequency and internal drive compatibility to avoid circuit redesign.
