1x 400ST / 400SR Ultrasonic Audio Piezo Transducer Receiver & Transmitter

1x 400ST or 400SR Ultrasonic Audio Piezo Transducer Receiver & Transmitter 

Brand New

The 400ST160 is a standard open type Transducer Transmitter consists of a piezoelectric ceramic disc mounted at the node of its fundamental resonant frequency, a conical metal resonator bonded at the centre of disc acting as a rigid piston. This special construction provides high sensitivity, wider bandwidth and excellent durability in wide temperature and humidity ranges and high stability in electrical and mechanical characteristics. Due to its free vibration character, the open type transducers are very suitable for continuous wave driving, such as Doppler motion detector.
