US M18 ultrasonic sensor
US 18 M 800 IU-B4
Article Number: 213063
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.
- 1 analog output (4…20 mA / 0…20 mA / 0…10 V)
- 1 Multi I/O (Switching Output, External Teach)
- Configuration via External Teach or IO-Link
- Configurable as an ultrasonic proximity sensor or barrier
- Teach modes (Single, Window, Two-Point, Reflex)
- Very short, robust metal design
- Synchronous and Multiplex Operation
