SBS12TMHMPPC

Overview

The SBS12TMHMPPC is an internally driven magnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 9 to 12V and draws between 40 and 250mA. The device produces a sound pressure level of 95dB at 9V measured from a distance of 10cm, with a resonant frequency of 2.075kHz. It features through-hole mounting via PC pins and has a physical diameter of 44.45mm.

Feature Summary

• Internally driven magnetic transducer design
• Through-hole PCB mounting configuration
• High sound pressure output capability

Applications

• Industrial alarm systems
• Medical device audio indicators
• General purpose audible alerts

Procurement Notes

Verify the specific suffix 'HMPPC' against official Mallory Sonalert documentation to confirm exact acoustic and electrical characteristics. Ensure compatibility with existing board layouts regarding the 44.45mm diameter and through-hole pin spacing. Confirm RoHS compliance status for your region before finalizing procurement.

Selection Notes

Select this component when a high-decibel audible alert is required without external driver circuitry. The internal drive simplifies schematic design compared to externally driven buzzers. Verify that the 9-12V operating range aligns with the system power supply rails and that the 2.075kHz frequency meets regulatory or user perception requirements.

Part Context

This part belongs to the Mallory Sonalert family of audio indicators and alarms. It is categorized under internally driven magnetic buzzers designed for industrial and medical applications. The product line emphasizes reliability and standardized form factors for easy integration into various electronic enclosures and panel mounts.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may differ in current draw, sound pressure levels, or mounting dimensions. Do not assume interchangeability based solely on voltage ratings.
