FT-32B-23E

RYD FT-32B-23E is a large-diameter piezoelectric ceramic buzzer disc for low-frequency sound indication in industrial alarms, security sirens and automotive warning equipment. The Ø32.0mm brass plate carries a Ø23.0mm ceramic disc and resonates at 2.3±0.5kHz with maximum resonant impedance of 500Ω, while static capacitance reaches 50.0nF at 1.0kHz for strong signal presence at up to 30Vp-p from -20℃ to +70℃, with insulation resistance of 100MΩ minimum at 25VDC. Manufactured under RYD ISO9001 quality system. Customization available: resonant frequency can be adjusted via dimension tuning, electrode pattern and lead wire connection are configurable, protective coating on the ceramic surface can be applied to your requirement, and waterproof or dustproof treatment is available; new designs can be developed for volume projects. Target scenarios: industrial alarm panels, security systems, automotive warning devices and medical equipment indication.
