The pulse ranging technology (PRT) from Pepperl+Fuchs can be used in sensors of all sizes for a wide range of applications. Unlike indirect processes such as phase correlation and analogue chip-based processes, the time of flight is measured directly. The first sensor with PRT is the cost-effective VDM28 distance sensor enclosed in a standard light barrier housing with a measurement range of 8m. The VDM100 distance measurement device offers a maximum range of 300m, a repeat accuracy degree of <0.5 mm. The VDM70 has a maximum range of 250m and is suitable for the simple positioning of gantry cranes, lifters, elevator cars or for measurement tasks, while the VDM54 with a maximum range of 6m is optimized for collision prevention applications on electronic suspended rails.
