SBT5PHFL

Overview

The SBT5PHFL is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for industrial audio indication. It operates on a DC input voltage range of 3.3V to 5VDC and produces a sound pressure level of 90dB. The device features an internal driver circuit and utilizes a flange mounting style with a diameter of 44.45mm. It is RoHS compliant and classified under industrial-grade audio indicators.

Feature Summary

• Piezoelectric technology with integrated internal driver circuitry
• Industrial-grade construction suitable for demanding environments
• Flange mounting design for secure panel integration

Applications

• Medical equipment audio signaling
• Industrial control panel alerts
• Perfusion pump status indicators

Procurement Notes

Verify the specific acoustic waveform variant required, as the SBT5PHFL designation indicates a particular sound profile within the SBT5 series. Confirm that the 3.3-5VDC operating voltage aligns with the target system power supply. Ensure the flange mounting dimensions are compatible with the enclosure cutout specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-voltage industrial buzzer is needed. The 90dB output provides clear audibility in moderate noise environments. The flange mount simplifies installation compared to bracket-mounted alternatives. Verify compatibility with IEC standards if used in regulated medical or safety applications.
