典型应用
Engineered for critical acoustic signaling, the ISU-3.2D50-T3 is a high-performance piezoelectric transducer (external drive buzzer) designed for precision and durability. Optimized at a resonant frequency of 3.2kHz—a range highly sensitive to the human ear—it delivers a powerful ≥80dB alert when driven by a square wave signal. This makes it the definitive solution for Automated Test Equipment (ATE) to signal pass/fail status, as well as for Industrial Automation panels and Smart City kiosks. Unlike fixed-tone active buzzers, this external drive unit offers superior reliability and longevity, providing clear, penetrating audio feedback for complex safety and monitoring systems.
