UW-09-515-S(S)

Overview

The UW-09-515-S(S) is an internally driven piezo alarm by Floyd Bell Inc. It operates within a voltage range of 5 to 15V DC and draws 35 to 80mA. The device produces a sound pressure level of 109dB at 15V with a frequency of 2.1kHz. It features panel mount installation via screw terminals, measures 35.81mm in diameter, and has a maximum seated height of 35.05mm.

Feature Summary

• Internally driven piezo technology for direct connection
• High output acoustic performance at standard voltages
• Robust panel mount construction with screw terminal interface

Applications

• Industrial equipment status indication
• Security system audio alerts
• Appliance operational warnings

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct electrical and mechanical specifications. Confirm that the operating voltage requirements align with the 5 to 15V DC range. Check for any environmental rating requirements such as IP68 if exposure to dust or water is expected. Ensure mounting dimensions match the enclosure design.

Selection Notes

Select this component when a high-decibel audible warning is required from a compact panel-mounted unit. The internal driver simplifies circuit design by eliminating external oscillators. Consider the 2.1kHz frequency for optimal human hearing sensitivity. Verify that the 35.81mm diameter fits the available panel space.

Part Context

This part belongs to the Floyd Bell Ultra Loud Piezo Alarm series. These devices are designed for applications requiring significant sound pressure levels from small form factors. The series typically includes variants with different voltage ranges and mounting options to suit diverse industrial and commercial environments.

Replacement Considerations

Check the UB-09-515-S(S) for similar electrical characteristics and IP68 rating. Compare the TMC-86-530-Q for voltage compatibility within the 5 to 30V range. Verify physical dimensions and terminal types before substitution.
