Overview
The SBT12GMHSPPC is a piezoelectric buzzer from the Mallory Sonalert industrial series, designed for through-hole mounting. It operates on a DC input voltage range of 9 to 12V and draws current at a level consistent with its internal driver circuitry. The device produces a general alarm sound pattern at a sound pressure level of 90dB. It features a circular form factor with a diameter of 44.45mm and utilizes PC pin termination for secure board integration.
Feature Summary
- Internal driver circuitry enables direct connection to DC power sources without external oscillators.
- Through-hole construction provides robust mechanical stability for industrial PCB applications.
- General alarm acoustic profile ensures high audibility in noisy operational environments.
Applications
- Industrial machinery status indication
- Process control panel alarms
- Equipment fault signaling systems
Procurement Notes
Verify that the target printed circuit board layout accommodates the specific through-hole pin spacing required by this component. Confirm that the operating environment remains within the specified electrical limits to ensure long-term reliability and compliance with safety standards.
Selection Notes
Select this model when a general alarm tone is required for industrial equipment monitoring. Ensure the application voltage aligns with the 9-12VDC specification. Consider the through-hole mounting requirement against available board space and assembly methods compared to surface-mount alternatives.
Part Context
This component belongs to the Mallory Sonalert SBT series, which specializes in industrial-grade audio indicators. The series is characterized by durable construction and standardized acoustic outputs suitable for demanding manufacturing and automation sectors where clear auditory feedback is critical for operational safety.
Replacement Considerations
Direct substitutes within the same series include SBT12TMFL for temperature-energy alerts and SBT12CMFL for cardiac patterns. Verify acoustic output requirements before swapping, as different suffixes denote distinct sound profiles rather than identical functional replacements.
