FT-45B-35E-230

RYD FT-45B-35E-230 is one of RYD’s largest piezoelectric ceramic buzzer discs, built for high-visibility audible signaling in alarm equipment and industrial systems. The Ø45.0mm brass plate resonates at 3.5±0.5kHz with maximum resonant impedance of 1000Ω and static capacitance of 60.0nF at 100Hz, producing a commanding tone at up to 30Vp-p from -20℃ to +70℃. Its large radiating surface makes it a strong fit for security sirens, industrial alarm panels, heavy-equipment warnings and applications where the sounder must be noticed immediately. Customization available: resonant frequency and impedance can be adjusted through dimension tuning, electrode configuration and lead wire connection are configurable, protective coating on the ceramic surface can be applied to your requirement, and waterproof or dustproof options are offered; new items can be developed for volume projects. Target scenarios: industrial alarms, security systems, automotive warning devices and heavy equipment.
