Prowave Ultrasonic Circular Proximity Sensor

The Prowave Pulse Burst transducer is optimized for echo ranging systems, featuring a centre frequency of 40.0 ± 1.0 kHz and a shorter ringing characteristic of 1.7 ms at 10 mV. It delivers a sound pressure level of 100 dB and has a bandwidth of 1.5 kHz. The typical beam angle is 100°, and it has a capacitance of 1400 ± 20% pF. This design makes it ideal for applications requiring precise timing and responsiveness.

Sensitivity is 78 dB
Maximum driving voltage is 20Vrms
Operation temperature is 30° to +70°C
