UW-09-515-S(S)D

Overview

The UW-09-515-S(S)D is a piezoelectric panel mount chime alarm manufactured by Floyd Bell Inc. It operates on a DC voltage range of 5 to 25 volts and draws between 5 and 25 mA. The device produces a sound pressure level of 70 dB at 5V measured from a distance of 61 cm. Its operating frequency is 2.9 kHz. The unit features wire leads for connection and has an IP68 rating, making it dust tight and waterproof. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm.

Feature Summary

• Piezoelectric technology for reliable acoustic output
• IP68 rated enclosure providing dust tight and waterproof protection
• Internally driven circuitry simplifies integration
• Panel mount design with top ported wire leads

Applications

• Industrial equipment status indication
• Appliance signaling systems
• Control panel audio alerts
• Outdoor electronic enclosures requiring environmental sealing

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct terminal type and mounting style. Confirm that the required drive voltage aligns with the 5 to 25 VDC specification. Check for UL or UR approval requirements if the end application mandates specific safety agency certifications. Ensure the physical dimensions fit the designated panel cutout space.

Selection Notes

Select this component when a sealed, internally driven chime is required for harsh environments. The IP68 rating distinguishes it from standard indoor units. Consider the 70 dB SPL output for applications needing moderate volume without external amplification. Verify that the 2.9 kHz frequency matches the desired auditory alert tone for the system.

Part Context

This part belongs to the AudioLarm II series of piezoelectric alarms. The series offers various voltage ratings and sound pressure levels. The UW prefix typically denotes a specific form factor within the lineup. This model provides a balance of environmental sealing and electrical simplicity for general industrial use.

Replacement Considerations

Cross-reference with other models in the AudioLarm II series for similar voltage and SPL ratings. Ensure any substitute maintains the IP68 rating and panel mount configuration. Verify compatibility with existing drive circuits before swapping components.
