UW-05-628-P(F)

Overview

The Floyd Bell UW-05-628-P(F) is a piezoelectric panel mount chime alarm belonging to the Audiolarm II series. It operates on a DC voltage range of 5 to 25 volts with an internally driven indicator circuit. The device generates a sound pressure level of 70 dB at 5V measured at a distance of 61 cm and functions at a frequency of 2.9 kHz. Power consumption ranges from 5 to 25 mA depending on the input voltage. The unit features wire leads for termination, with ports located on the top side. It is rated IP68 for dust tightness and waterproofing, ensuring reliable operation in harsh environments. The operating temperature range spans 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 dust tight and waterproof protection for demanding environments
• Internally driven piezoelectric mechanism requiring no external driver circuitry
• Wide DC voltage compatibility allowing operation across 5 to 25 volt systems
• Panel mount construction with top-mounted ports and wire lead terminations

Applications

• Industrial machinery status indicators
• Marine equipment audible alarms
• Outdoor control panel signaling
• Heavy-duty appliance chimes

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact acoustic and electrical characteristics. Ensure the required mounting hole diameter matches the physical specifications provided in the datasheet. Confirm that the operating environment temperature remains within the specified -20°C to 65°C range. Validate that the application voltage falls within the 5 to 25 VDC operational window to prevent damage or malfunction.

Selection Notes

Select this component when high ingress protection is required for audible signaling in wet or dusty conditions. The wide voltage range simplifies integration into various power supply architectures without additional regulation. The internally driven design reduces bill of materials complexity by eliminating the need for separate driver transistors or logic circuits. Consider the physical size constraints during PCB or panel layout planning.

Part Context

This part belongs to the Audiolarm II series of piezoelectric chimes manufactured by Floyd Bell Inc. The series is characterized by robust construction suitable for industrial applications. Similar models in the lineup may offer different voltage ratings, sound pressure levels, or mounting configurations while maintaining the same fundamental piezoelectric technology and internal drive architecture.

Replacement Considerations

Cross-reference with other Floyd Bell Audiolarm II models for direct mechanical and electrical compatibility. Verify that any substitute maintains the IP68 rating if environmental sealing is critical. Ensure the replacement part supports the same DC voltage range and provides equivalent acoustic output for the specific application requirements.
