SBM616PU

Overview

The SBM616PU is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 22 to 28 VDC and draws a current of 40 mA. The device produces a warble tone at a frequency of 2.8 kHz with a sound pressure level of 77 dBA measured at 10 cm. Designed for through-hole mounting, it features screw terminals for electrical connection. The unit measures 43 mm in diameter and 35.56 mm in height, operating reliably within a temperature range of -30°C to 65°C.

Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Warble tone output optimized for audible alert applications
• Screw terminal connections providing secure panel mount installation

Applications

• Industrial control panels requiring visual and audible alarms
• Medical equipment status indication systems
• Transportation vehicle monitoring interfaces

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct terminal type and acoustic characteristics. Confirm that the required operating voltage aligns with the 22-28 VDC specification. Check for updated RoHS compliance certificates if environmental regulations apply to your region. Ensure panel cutout dimensions match the 43 mm diameter requirement for proper mechanical fitment during assembly.

Selection Notes

Select this component when a high-intensity warble alarm is needed for industrial environments. The internal driver simplifies design by removing external oscillator requirements. Compare the 77 dBA output against ambient noise levels to ensure audibility. Consider the screw terminal style if vibration resistance is critical for the installation site compared to quick-connect alternatives.

Part Context

This part belongs to the SBM series of panel-mount buzzers from Mallory Sonalert. The series focuses on robust audio indicators for commercial and industrial use. It shares the same form factor as other SC series devices but differs in drive electronics and acoustic profile. The manufacturer maintains this line to provide reliable signaling solutions for heavy-duty applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB layouts or panel mounts before considering alternative models from different manufacturers.
