Procurement Notes

Verify the specific suffix and electrical ratings against the official Mallory Sonalert datasheet before procurement. Confirm that the 9-12VDC operating range matches the target system power supply. Ensure the flange mounting dimensions are compatible with the intended enclosure cutout. Check for any regional compliance requirements such as CE or UL certification relevant to the deployment location.

Selection Notes

Select this component when a compact, internally driven piezoelectric buzzer is required for industrial or medical environments. The 9-12VDC input range suits standard low-voltage control circuits. The flange mount provides a robust mechanical connection compared to through-hole options. Consider the 90dB SPL output for audible alerts in moderately noisy settings.

Part Context

This part belongs to the SBT series of industrial-grade audio indicators from Mallory Sonalert. The series is characterized by robust construction and compliance with international safety standards. These devices are commonly used in heavy machinery, medical equipment, and transportation sectors where reliable visual and auditory warnings are critical for operational safety.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure replacement parts match the 9-12VDC input, 1.25kHz frequency, and 44.45mm flange mounting dimensions. Verify that alternative components maintain equivalent sound pressure levels and environmental certifications.
