The U18T ultrasonic sensors in the widely used M18 format combine robust construction with intelligent technology. The M18 thread design offers a clear advantage: It enables fast, tool-free and efficient installation. Due to their high stability and reliability, U18T sensors are suitable for a wide range of applications with a detection range of up to 2,400 mm. They are ideal for detecting shiny, transparent and dark objects and can even reliably detect mirrored surfaces. With their integrated IO-Link interface, they offer additional flexibility and easy integration into various systems.

Common Cylinder Designs with M18 Thread for Easy Installation


This video shows a practical example demonstrating how quickly and easily the U18T ultrasonic sensors can be installed. Installation is extremely efficient and easy thanks to the widely used threaded design.

Possible Uses for U18T Ultrasonic Sensors

Object Detection

In the food industry, baked goods are transported in boxes through the various process steps. Before cleaning the boxes, it has to be ensured that there is no product left in the boxes. For this purpose, two ultrasonic distance sensors are installed next to each other above the conveyor belt, which emit ultrasonic waves and thus check the contents of the boxes.

Presence Check

In the furniture industry, wooden panels with different colors, shapes, degrees of gloss and surfaces are conveyed on roller conveyor belts to the next process step. In order to monitor the transport fully automatically, the presence of the panels must be recorded at all times.
