UB-09-628-Q(F)

Overview

The UB-09-628-Q(F) is an internally driven piezoelectric alarm from Floyd Bell Inc. It operates within a voltage range of 6 to 28 Vdc and draws 20 to 50 mA. The device produces a sound pressure level of 109 dB at 28V measured at 61cm. Its center frequency is 2.1 kHz with a tolerance of +/- 250 Hz. The unit features a panel mount design with a diameter of 35.81mm (1.410 inches) and a maximum seated height of 35.05mm (1.380 inches). Electrical connections are made via quick connect tabs measuring 0.250 inches.

Feature Summary

• Internally driven piezoelectric technology for direct connection to power sources
• High-output acoustic performance delivering 109 dB sound pressure level
• Panel mount construction with quick connect tab terminals for simplified installation

Applications

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

Procurement Notes

Verify the specific suffix configuration, as variants such as Q(S)D or F may denote differences in tone or terminal style. Confirm that the operating voltage aligns with the 6-28 Vdc specification. Ensure the mounting hole diameter accommodates the 35.81mm body size. Check for RoHS compliance requirements if applicable to your assembly standards.

Selection Notes

Select this component when a high-decibel audible warning is required without external driver circuitry. The wide voltage range supports various DC supply systems. The panel mount form factor suits enclosures requiring front-accessible alarms. Consider the 2.1kHz frequency for optimal human audibility in noisy environments.

Part Context

This part belongs to the Floyd Bell Ultra Panel Mount Alarm series. These devices are designed for robust industrial and commercial applications. The series typically includes variations in tone, voltage, and mounting styles. The piezoelectric element provides reliable long-term operation compared to magnetic alternatives.

Replacement Considerations

Direct substitutes include the UB-09-628-Q(S)D and UB-09-628-S(F)D. Verify that replacement units match the 35.81mm diameter and 109dB SPL rating. Ensure the terminal type matches the existing wiring harness.
