SBT5THFL

Overview

The SBT5THFL is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. Designed for robust audio indication, this component operates within a voltage range of 3.3 to 5 VDC and delivers a sound pressure level of 90 dB. It features a drug-fluid resistant construction suitable for harsh environments and complies with RoHS standards. The unit utilizes a through-hole mounting style and includes internal driving circuitry for direct interface with control logic.

Feature Summary

• Drug-fluid resistant housing for durability in chemical environments
• Internal driver circuitry simplifies integration with low-voltage systems
• Industrial-grade construction meets stringent environmental standards

Applications

• Medical equipment requiring fluid-resistant audio alerts
• Industrial control panels exposed to cleaning agents
• Safety warning systems in pharmaceutical manufacturing

Procurement Notes

Verify the specific suffix requirements against your design specifications before ordering. Confirm that the 3.3-5VDC operating range aligns with your system power supply. Ensure the physical dimensions and mounting hole patterns match your enclosure design constraints. Check for any regional compliance certifications required for your target market.

Selection Notes

Select this model when high reliability in fluid-exposed environments is critical. The integrated driver reduces component count compared to passive buzzers. Consider the 90 dB output level for applications requiring clear audible warnings without excessive power consumption. Evaluate the through-hole mounting option for secure mechanical attachment in vibrating environments.

Part Context

This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. The series is known for combining piezoelectric technology with ruggedized housings. Similar models in the lineup may vary in voltage ratings or acoustic output levels while maintaining the same form factor and mounting characteristics.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify pin compatibility and acoustic performance if considering alternative brands. Ensure any replacement maintains the drug-fluid resistance rating and voltage specifications.
