FT-34.5S-32S8

RYD FT-34.5S-32S8 is a heavy-duty piezoelectric ceramic buzzer disc on thick stainless steel plate, engineered for demanding alarm applications. The Ø34.55mm SUS plate and Ø25.0mm ceramic disc resonate at 3.2±0.5kHz with electrostatic capacitance of CM 35.0nF±30% and CF 3.0nF±30% at 100Hz, accepting up to 30Vp-p input from -20℃ to +70℃. The 0.30mm plate gives the element extra mechanical strength for use in automotive alarms, outdoor security sirens, agricultural machinery and equipment exposed to vibration and rough handling. Customization available: resonant frequency can be tuned through dimension adjustment, electrode pattern and lead wire connection are configurable, protective coating on the ceramic surface can be applied per your design, and waterproof or dustproof treatment is offered for outdoor service; new designs are available for volume projects. Target scenarios: automotive alarms, security sirens, industrial equipment and outdoor warning systems.
