DI-Soric US 18 M 1500 IU-B4 US M18 ultrasonic sensor

The US-M18 is the standard variant in a short design, which makes this sensor very compact. It is suited for medium ranges and can be operated to switch or to measure. Thanks to three modes and other settings, the auto-teach is exceptionally easy. IO-Link ensures a constant monitoring of the device functions and parameters and offers extended adjustment options.
