FT-41B-10TE

RYD FT-41B-10TE is an ultra-large thin-profile piezoelectric ceramic buzzer disc that combines far-reaching low-frequency sound with a slim 0.22mm total thickness. The Ø41.0mm brass plate works with a Ø25.0mm ceramic disc at a resonant frequency of 1.0±0.3kHz, while static capacitance of 90.0nF at 100Hz supports strong signal output at up to 30Vp-p from -20℃ to +70℃. The deep tone and large radiating area suit outdoor alarms, automotive reversing warnings, security sirens and industrial signaling where audibility at distance matters. Customization available: resonant frequency can be tuned via 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 available for outdoor installations; new designs can be developed for volume projects. Target scenarios: outdoor warning devices, automotive alarms, security sirens and industrial equipment.
