Overview
The SBT12XMHSPPC is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 9 to 12V and draws current consistent with its internal driver circuitry. The device produces a sound pressure level of 90dB at a distance of 10cm, emitting a tone specifically designated for oxygen alarm applications. It features a round shape with a diameter of 44.45mm and a height of 15mm. The unit is designed for PCB mount installation using solder terminals and functions within a temperature range of -30°C to +65°C.
Feature Summary
- Internally driven piezoelectric technology eliminates the need for external oscillators
- Emits a specific acoustic signature designated for oxygen alarm identification
- Designed for direct printed circuit board mounting via solder terminals
Applications
- Medical equipment oxygen alarm systems
- Industrial safety warning indicators
- Healthcare device status alerts
Procurement Notes
Verify the specific acoustic designation matches the target application requirements, as this unit is configured for oxygen alarms. Confirm that the PCB layout accommodates the 44.45mm diameter and 15mm height constraints. Ensure the operating environment remains within the specified -30°C to +65°C thermal limits. Check for RoHS compliance documentation if required by project specifications.
Selection Notes
Select this component when a dedicated oxygen alarm tone is required in medical or industrial settings. The internal drive simplifies circuit design by removing the need for external driving components. Consider the PCB mount style and solder termination method during mechanical integration. Verify that the 9-12VDC supply aligns with the system power architecture.
Part Context
This part belongs to the SBT series of audio indicators from Mallory Sonalert. The series includes various models differentiated by acoustic output and specific alarm tones for different medical gases and safety conditions. The SBT12XMHSPPC is distinct due to its oxygen-specific designation and PCB mount form factor.
Replacement Considerations
Substitute only with other SBT series units if the specific oxygen alarm tone is not critical. Verify that any replacement maintains the same voltage range, mounting style, and dimensional envelope to ensure compatibility with existing PCB layouts.
