Overview
MA40S4S / MA40S4R are ultrasonic transducer for various detections. MA40S4S is used to transmit ultrasonic waves. MA40S4R is used to receive them.
MA40S4S / MA40S4R consist of piezoelectric ceramics, metal plate, resonator and resin case. Resonator has like a funnel shape to transmit ultrasonic waves which is generated by vibration of resonator to the air efficiently(or to concentrate ultrasonic waves...
