Overview
The SBS300FL is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates at a frequency of 325Hz with a sound pressure level of 95dBA at 10cm when driven by 9V, or 100dB at 325Hz with an 8-ohm impedance in speaker configurations. The device features flange mounting and utilizes wire leads for connection. It is designed for industrial applications requiring reliable acoustic signaling.
Feature Summary
- Piezoelectric transducer technology for consistent acoustic output
- Flange mount design for secure panel installation
- Internal driver capability for direct voltage application
- Compatible with external amplifier circuits via low impedance
Applications
- Industrial machinery status indicators
- Vehicle warning systems
- Appliance alert signals
- Security system alarms
Procurement Notes
Verify the specific datasheet version to confirm electrical parameters such as drive voltage and current consumption. Ensure the mounting hole diameter matches the flange specifications. Confirm RoHS compliance status if required for your assembly process. Check for any lead-free soldering requirements during procurement.
Selection Notes
Select this component when a high-intensity audible alert is required in space-constrained panels. The flange mount simplifies installation compared to bracket-mounted alternatives. Consider the 8-ohm impedance if driving from a standard audio amplifier rather than a direct DC source. Evaluate the 325Hz tone for optimal human audibility in noisy environments.
Part Context
This part belongs to the Mallory Sonalert family of audio indicators. It is distinct from internally driven buzzers that operate on simple DC voltages without external amplification. The SBS300FL bridges the gap between simple piezo buzzers and complex electronic sirens, offering a robust mechanical solution for harsh environments.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 325Hz frequency, 95-100dB SPL, and flange mounting dimensions. Verify electrical compatibility before substitution.
