Overview
The SBT12TMHSPPC is a board-mount audio indicator manufactured by Mallory Sonalert. It operates within an IEC voltage range of 9 to 12 VDC and produces a sound pressure level of 90 dB. The device features a temperature-energy alarm tone profile, suitable for thermal monitoring applications. It utilizes through-hole solder pin termination for PCB integration. The component complies with RoHS standards and is supplied in a stick packaging format.
Feature Summary
- Generates a distinct temperature-energy alarm tone for specific alert scenarios
- Operates on standard IEC DC voltage ranges between 9V and 12V
- Provides high-volume acoustic output rated at 90 dB
- Designed for direct surface mounting via solder pins
Applications
- Thermal energy system monitoring
- Temperature alarm indication circuits
- Industrial equipment status signaling
- HVAC control panel alerts
Procurement Notes
Verify the exact suffix configuration against the manufacturer's current datasheet to ensure compatibility with specific enclosure or environmental requirements. Confirm that the 9-12VDC operating range aligns with the target circuit design. Check for any recent updates to the RoHS compliance documentation or lead times, as availability may vary by region.
Selection Notes
Select this model when a dedicated temperature-related alarm tone is required rather than a generic beep. Ensure the application environment supports the specified 9-12VDC input without significant voltage drop. Consider the 90 dB output level relative to ambient noise levels to guarantee audibility. Verify that the board-mount form factor fits the available PCB space constraints.
Part Context
This component belongs to the SBT series of industrial-grade audio indicators from Mallory Sonalert. The series is characterized by robust construction and specific tone profiles tailored for critical industrial alerts. The SBT12TMHSPPC variant specifically addresses thermal monitoring needs within this lineup.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Potential alternatives may include other SBT series models with different voltage ratings or tone profiles, provided they meet the mechanical and electrical interface requirements.
