Open Type Ultrasonic Sensors

High sound pressure, high sensitivity sensor with unimorph and radial cone construction.

Open type is especially designed for air medium application.

Low reverberation type is also available for pulsed driving.

Standard housing size : Φ8, Φ10, Φ16[mm]

Standard frequency : 32, 40[kHz]
