Prowave Ultrasonic Circular Proximity Sensor [250SR180]; 204-878

The Prowave Air Ultrasonic Ceramic Transducers operate at a centre frequency of 25.0 ± 1.0 kHz, with bandwidth of 1.8 kHz. They deliver a minimum transmitting sound pressure level of 112 dB at 25.0 kHz when driven at 10 Vrms from 30 cm. The receiving sensitivity is 62 dB at the same frequency. With a capacitance of 2400 pF at 1 kHz, they can withstand a maximum driving voltage of 20 Vrms. The total beam angle is typically 95° at 6 dB, making these transducers suitable for various ultrasonic applications.
