MA40S4S

MA40S4S is an ultrasonic transducer for various detections. MA40S4S is used to transmit ultrasonic waves. It consists 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.) is the most important characteristic for ultrasonic transducers. For example, in measuring distance application, high S.P.L. transducer enables to detect the further distance. Suitable for object detection, measuring the distance and dynamic body detection.
