Product Overview
The 16mm and 19mm high-decibel metal buzzers with indication are compact yet powerful signaling devices designed for industrial and commercial applications.

16mm Buzzer: This ultra-compact model is ideal for space-constrained environments. Despite its small size, it delivers a sound pressure level of 80–105 dB and features a built-in LED indicator. Available in various voltages (6V, 12V, 24V, 36V, 110V, 220V), it ensures clear alerts in machinery, control panels, and automation systems. 

19mm Buzzer: Offering a slightly larger footprint, the 19mm buzzer provides enhanced acoustic output, making it suitable for environments with higher ambient noise levels. It maintains the same voltage versatility and includes an LED indicator for visual alerts.
