Pro-Wave Electronics 400ST/R100 Air Ultrasonic Ceramic Transducers

Pro-Wave Electronics 400ST/R100 Air Ultrasonic Ceramic Transducers are suitable for continual wave driving, such as Doppler motion detectors. A piezoelectric ceramic disc is mounted on the node of the fundamental resonant frequency, and a conical metal resonator is bonded at the center of the disc that acts as a rigid piston. The special construction of Pro-Wave Electronics 400ST/R100 Air Ultrasonic Ceramic Transducers provides high sensitivity, a wider bandwidth, excellent durability in wide temperature and humidity ranges, and vibration-free usage.
