Balluff's Non-Contact Ultrasonic Sensors
Non-contact ultrasonic sensors measure fill levels, heights and sag; count and monitor the presence of objects; and operate independently of color and surface finish. Detection ranges extend from 20 mm to 8 m, and they are available in switching or analog versions. All analog versions are available with voltage or current output (0–10 V or 4–20 mA). M30 version includes variants with two switching outputs.
