Ultrasonic Solutions

Banner Engineering Ultrasonic Solutions provide non-contact sensing for industrial applications that require reliable detection or the measurement of challenging targets. The sensors use high-frequency sound waves instead of light, enabling object detection regardless of color, transparency, reflectivity, or surface finish. The sensors measure the target's presence and position by emitting sound waves and analyzing the reflected echoes. The sensor lineup offers a wide variety of housings, mounting styles, sensing distances, and output configurations, such as discrete, analog, relay, and wireless serial. These ultrasonic solutions from Banner Engineering deliver stable performance with liquids, clear objects, uneven surfaces, and objects in dirty environments.
