FGBS-39S2-08TEC150

RYD FGBS-39S2-08TEC150 is a large-diameter piezoelectric ceramic buzzer disc for industrial alarm and warning applications. The Ø39.0mm SUS304 stainless steel plate works with a Ø25.0mm ceramic disc at a resonant frequency of 0.8±0.3kHz, delivering a strong low-pitched tone for alarms, sirens, automotive reversing warnings and heavy-equipment signaling. Static capacitance reaches 390nF at 100Hz, allowing flexible matching with drive circuits, and the disc accepts up to 30Vp-p input from -20℃ to +70℃. Manufactured under RYD ISO9001 quality system. Customization available: resonant frequency and impedance 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 use; new designs are available for volume projects. Target scenarios: industrial alarm panels, security sirens, automotive warning devices and general audible indication equipment.
