Ultrasonic Sensor, Receiver, MA40 Series, 9.9 mm Diameter, 40 kHz, -63 dB, -40 °C to 85 °C 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) Product Information Sensing Range Min: 200mm Sensing Range Max: 4m Beam Angle: 80° Switching Frequency: 40kHz External Diameter: 9.9mm Sensitivity (dB): -63dB Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: MA40 Series
