Pro-Wave Electronics 400ST/R160 Air Ultrasonic Ceramic Transducers

Pro-Wave Electronics 400ST/R160 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. This special construction is vibration-free and provides high sensitivity, a wider bandwidth, and excellent durability in wide temperature and humidity ranges.
