TXB-86-515-S(F)

Overview

The TXB-86-515-S(F) is an internally driven piezoelectric buzzer from the Floyd Bell Turbo series, designed for panel mounting. It operates on a DC input voltage range of 5 to 15 Vdc with a typical operating current of 30 mA. The device generates an extra loud fast beep tone at a frequency of 2900±250 Hz. Acoustic performance reaches 103 dBA at 15V and 92 dBA at 5V, measured at a distance of 2 feet. The unit features a 33.02 mm diameter housing suitable for industrial and consumer electronics indicator applications.

Feature Summary

• Internally driven piezoelectric design eliminates need for external oscillators
• Produces extra loud fast beep tone for high visibility alerts
• Panel mount construction for secure installation in enclosures
• Wide operating voltage compatibility from 5V to 15V DC

Applications

• Industrial equipment status indicators
• Consumer electronics alarm systems
• Security system acoustic signaling
• Medical device alert notifications

Procurement Notes

Verify exact acoustic output specifications against the official datasheet, as sound pressure levels vary with applied voltage. Confirm mechanical dimensions match panel cutout requirements before integration. Ensure supply chain sources provide genuine Floyd Bell components to guarantee reliability and compliance with RoHS standards for lead-free manufacturing.

Selection Notes

Select this component when high audible volume is required within a compact form factor. The internal drive circuit simplifies PCB layout by removing external oscillator requirements. Consider the 5-15V operating range for systems with variable power supplies. Verify that the 2900 Hz frequency aligns with human hearing sensitivity for optimal alert effectiveness in noisy environments.

Part Context

This part belongs to the Floyd Bell Turbo series of piezoelectric buzzers, characterized by high sound pressure levels relative to size. The TXB-86-515-S(F) variant specifically targets applications requiring reliable acoustic signaling without complex driving circuits. Its panel mount design distinguishes it from surface-mount alternatives, offering robust mechanical stability for permanent installations in various electronic assemblies.

Replacement Considerations

Direct substitutes include the TXB-86-515-Q(F) for broader voltage tolerance up to 30V. The TXB-86-515-S(S) offers similar acoustic characteristics with potential packaging differences. Verify pinout compatibility and mounting hole alignment when cross-referencing with other Floyd Bell models or third-party piezoelectric buzzers with identical 33mm diameter specifications.
