SBT12GMHCTPC

Overview

The SBT12GMHCTPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features an internally driven circuit and operates on DC input within a voltage range of 9 to 12VDC. The device produces a general alarm sound at a frequency of 2.075kHz with a sound pressure level of 90dB. Electrical consumption is specified between 15mA and 25mA, and the acoustic output measures 85dB at a distance of 10cm. The unit utilizes a threaded mounting style with a diameter of 44.45mm and supports an operating temperature range from -30°C to +65°C.

Feature Summary

• Internally driven piezoelectric technology for simplified integration
• Threaded mounting design for secure panel installation
• Compliance with IEC standards for industrial reliability

Applications

• Industrial machinery status indication
• General purpose audio alarms
• Equipment fault signaling

Procurement Notes

Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure correct acoustic pattern and mounting specifications. Confirm that the 9-12VDC input requirement aligns with the target system power supply. Check for RoHS compliance documentation if environmental regulations apply to the deployment environment.

Selection Notes

Select this component when a robust, internally driven piezo buzzer is required for industrial environments. The 44.45mm threaded form factor suits standard panel cutouts. Ensure the 90dB output meets audible requirements for the specific application noise floor. Verify that the -30°C to +65°C operating range covers the expected ambient conditions.
