SICK has a wide range of optic and ultrasonic solutions that measure from sub-microns to kilometers.
They solve measuring, detecting and positioning applications using triangulation and time-of flight modes.
Sensors using triangulation are ideal for short-range, highly precise measurement. They can inspect miniature parts, thickness and shape, etc. Time-of-flight sensors work at longer distances, are not influenced by reflectivity or ambient light − perfect for positioning AS/RS, rail cars and gantry cranes.
