Overview
The Mallory Sonalert SBT5GHFL is a piezoelectric buzzer designed for audible signaling applications. It operates at a nominal voltage of 5V DC and produces a sound pressure level of approximately 85 dB at a distance of 10 cm. The device features a flat tone frequency centered around 2.7 kHz. Constructed with a black epoxy-coated steel case, it offers environmental protection suitable for general industrial use. The component utilizes a through-hole mounting configuration with two leads for electrical connection.
Feature Summary
- Piezoelectric transduction mechanism for reliable acoustic output
- Epoxy-coated steel housing providing environmental durability
- Through-hole lead termination for standard PCB integration
Applications
- General purpose alarm systems
- Appliance status indicators
- Industrial control panel signaling
Procurement Notes
Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm lead availability and packaging format directly with authorized distributors prior to ordering. Cross-reference part numbers to avoid substitutions that may alter electrical characteristics or physical dimensions.
Selection Notes
Select this component when a moderate sound pressure level is sufficient for the intended environment. Ensure the operating voltage matches the system supply to prevent damage or insufficient output. Consider the physical size constraints of the enclosure during mechanical design. Verify that the through-hole footprint aligns with the target printed circuit board layout.
Part Context
This model belongs to the SBT series of piezoelectric buzzers from Mallory Sonalert Products Inc. The series is characterized by compact form factors and robust construction materials. These components are engineered for cost-effective audible notification in consumer and industrial electronics where high-fidelity audio is not required.
Replacement Considerations
Consult official substitution guides for equivalent models with matching voltage and acoustic output. Verify pinout compatibility before replacing existing units. Ensure replacement parts meet the same environmental rating standards as the original specification.
