UB-19-230-S(S)

Overview

The UB-19-230-S(S) is a piezoelectric panel-mount buzzer from Floyd Bell Inc. It operates on a voltage range of 20 to 30V AC or DC. The device features an internally driven indicator circuit and produces a sound pressure level of 109dB at 30V measured at a distance of 61cm. Its operating frequency is 2.1kHz. The unit has a maximum seated height of 46.74mm (1.840 inches) and utilizes quick connect blades with screws for mounting.

Feature Summary

• Internally driven piezoelectric technology for direct connection
• Panel mount design with quick connect blade terminals
• High sound pressure output capability

Applications

• Industrial control panels requiring audible status indication
• Equipment alarm systems operating within 20-30V ranges
• Security system sirens and warning devices

Procurement Notes

Verify the specific suffix designation, as variations such as (F) or (S) may indicate differences in terminal configuration or tone characteristics. Confirm that the required voltage range aligns with the 20-30V specification. Ensure the mounting hole dimensions accommodate the 35.81mm diameter and check that the 46.74mm height fits within the enclosure constraints. Cross-reference datasheets for exact terminal types.

Selection Notes

Select this component when a high-decibel audible alert is required for industrial environments. The internally driven nature simplifies circuit design by eliminating external oscillators. Consider the 2.1kHz frequency for optimal human hearing sensitivity. Verify compatibility with existing panel cutouts and wiring harnesses utilizing quick connect blades.

Part Context

This model belongs to the Floyd Bell piezoelectric buzzer family, designed for robust industrial applications. It shares the Turbo series characteristics of internal driving circuits. Similar models like the UB-19-230-S(F) exist, potentially differing in terminal style or acoustic tuning. The product remains active in the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include the UB-19-230-S(F), which shares identical electrical parameters but may differ in terminal construction. Other compatible units within the same voltage and size class should be evaluated for SPL and frequency matching.
