Murata (MA40S4S) Ultrasonic Sensor, Transmitter, MA40 Series, 9.9 mm

Ultrasonic Sensor, Transmitter, MA40 Series, 9.9 mm Diameter, 40 kHz, -63 dB,-40 °C to 85 °CProduct OverviewThe MA40S4S from Murata is an open structure ultrasonic sensor. Ultrasonicsensor features a composite oscillating body combining the oscillator whichjoins a metal plate and piezoelectric ceramics with a resonator. The body iselastically fixed to the base and housed in a case. The resonator is shaped likea funnel to efficiently radiate the ultrasonic waves generated by theoscillating body into the air and to effectively concentrate ultrasonic wavesfrom the air on centre of the oscillator. Sound pressure is the most importantparameter of open structure ultrasonic sensors. In distance measurementapplications, the higher the sound pressure of the ultrasonic sensor, the longerthe sensor range.10mm size diameterTransmitter for dual use typeNominal frequency is 40KHzOperating temperature range from -40°C to 85°CSensitivity is typically -63dBSound Pressure is 120dBDirectivity is 80°Capacitance is 2550pFDetectable range upto 4mAllowable input voltage is 20Vpp at 40KHzApplicationsSensing & Instrumentation, SecurityProduct InformationSensing Range Min: 200mmSensing Range Max: 4mBeam Angle: 80°Switching Frequency: 40kHzExternal Diameter: 9.9mmSensitivity (dB): -63dBOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: MA40 Series
