Open-Type Ultrasonic Sensors: Smart Detection & Directional Audio Solutions

ADW’s open-type ultrasonic sensor series offers a range of models in various sizes, including the newly released 8mm sensor—currently one of the smallest in the domestic market.

These sensors operate using the piezoelectric effect to generate ultrasound, without relying on coil structures. They offer excellent directionality and penetration, performing reliably even in dusty or electromagnetically noisy environments, and are unaffected by color or surface temperature of objects.
