Datasensor M30x1 ultrasonic sensors of Datalogic US30 series are available in models with operating distances reaching 200 cm either with bipolar digital output (1 NPN and 1 PNP) or with 4-20 mA or 0-10 V analogue output. The sensors can be easily configured using the Teach-in function, while the operating status is visibly signalled by 3 LEDs. The temperature compensation function corrects the sound speed changes due to temperature variations, so the sensor precision remains unchanged in all situations.
