SICK has released the VTB 18 cylindrical photoelectric switch with background suppression. It has an extremely small light spot, with which narrow or dark objects are reliably detected. The scanner's operating distance lies between 30mm and 130mm. Users can simply set the scanning distance by potentiometer.
It also offers background suppression. The small transition zone between the scanning distance and the background allows precise object detection without interference from the immediate background.
Visible red light transmission and a light spot on the object simplify alignment of the scanner during installation and commissioning.
