DI-Soric US 12 M 150 FB IU-B4 Ultrasonic sensor US-M12

The US-M12 is the compact class of ultrasonic sensors in the M12 housing. Equipped with an IO-Link interface, the sensor can be operated to switch or to measure. The sensitivity can also be adjusted via auto-teach, so the sensor is thus operational within a few seconds.

• IO-Link
• Configurable as an ultrasonic sensor or barrier
• 3 different teach modes
• Working range adjustable
• Very narrow detection lobe / no blind area due to focus nozzle
• Switching functions: Closer/opener, window function teachable
• Resistant to dirt
• Small design
• Robust metal housing
• Protection class IP 67
