SICK has released the new Ax20 line sensor for edge detection and positioning control, with fast web edge and line tracking.

According to Sick, the Ax20 has a high-resolution array line which allows it to detect a diverse range of objects with a repeat accuracy of 50µm.

Sick says the measuring range of the scanning Ax20 can be up to 30mm wide, and object detection is independent of the reflectance properties of material surfaces, having deliver precise and reliable results all the time.

Sick claims the Ax20 line sensor has typical applications in the acquisition of measured values for controlling the web edges of continuous materials, such as films or paper, whose passage can be readjusted via the signals of the analogue 4-20mA output.
