Data Sheet MA40S4S/MA40S4R MA40S4S/MA40S4R Ultrasonic Sensor Open Structure Type Features  High S.P.L. and high sensitivity  Compact size(10.0mm dia.)  Open type structure (indoor applications) Applications  Object detection  Measuring the distance  Dynamic body detection 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 from the air on the center of resonance).Sound pressure level(S.P.L.
