Product Overview
MA40S4R is an ultrasonic receiver sensor. 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 centre 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.
- High S.P.L. and high sensitivity
- Compact size(10.0mm dia.)
- Open type structure (used for indoor applications)
Notes
It cannot be used in outdoor applications and cannot be used for automotive applications.
