Overview
The SBT12TMPC is a piezoelectric buzzer from Mallory Sonalert, designed for industrial applications. It operates within a voltage range of 9 to 12 VDC and produces a sound pressure level of 90 dBA. The device features a continuous tone at a frequency of 3 kHz. It utilizes solder pin termination and supports panel mount installation. The unit is RoHS compliant and includes a stackable design for multi-unit configurations.
Feature Summary
- Piezoelectric technology for reliable audio signaling
- Stackable mechanical design for compact assembly
- Industrial-grade construction for durability
Applications
- Industrial machinery status indication
- Medical equipment alarm systems
- Transportation vehicle signaling
Procurement Notes
Verify the specific suffix 'PC' against official Mallory Sonalert documentation to confirm exact electrical and mechanical specifications. Ensure compatibility with existing panel mounting holes and soldering processes. Confirm RoHS compliance status through current manufacturer datasheets before integration into regulated environments.
Selection Notes
Select this component when a 90 dBA continuous alert is required in confined spaces. The stackable form factor allows vertical integration without increasing footprint. Verify that the 9-12 VDC operating range matches the system power supply. Ensure the solder pin termination method aligns with the PCB layout or wiring harness design.
Part Context
This part belongs to the SBT series of piezoelectric buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by its stackable architecture, enabling multiple units to be mounted vertically. This design reduces the horizontal space required for alarm assemblies in dense electronic enclosures.
Replacement Considerations
Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may not match the stackable mechanical interface or specific acoustic output requirements.
