Banner's U-GAGE ULTRA-BEAM Ultrasonic Sensors enable users to detect and distinguish material adjacency, despite varying color or translucence, via an electrostatic ultrasonic transducer. This transducer also enables long-range recognizing and triangulating (0.5-6 meters), and is available in both DC and AC designs. They integrate seamlessly to PLCs, multiple-speed drives, and microprocessors as well.
