概要
The PB series are high-performance buzzers with a unimorph piezoelectric ceramic element and an integral self-excitation oscillator circuit.
用途
Fire alarms, smoke detectors, home security systems, call buzzers, car alarm systems, clocks, and cash registers.
特点
They exhibit extremely low power consumption in comparison to electromagnetic units.They are constructed without switching contacts to ensure long life and no electrical noise.Compact, yet produces high acoustic output with minimal voltage.
