FT-50T-2.8B

RYD FT-50T-2.8B is a 50mm-diameter piezoelectric ceramic buzzer disc engineered for extreme-temperature audible signaling. With an operating range extended to -30℃ to +70℃, the Ø50.0mm brass plate delivers a deep 2.8±0.5kHz tone with static capacitance of 35.0nF at 100Hz, maximum resonant impedance of 200Ω and allowable input up to 30Vp-p. The wide temperature margin makes it suitable for automotive reversing alarms, outdoor warning systems, cold-chain equipment and applications operating in harsh climates. 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 exposure; new designs can be developed for volume projects. Target scenarios: automotive alarms, outdoor warning equipment, cold-chain and industrial devices.
