Description

US M18 ultrasonic sensor

US 18 M 1500 IU-B4
Article Number: 213065

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.
