The DMP 2 position finder is an optoelectronic sensor which is used for fine positioning in handling and warehousing systems. At, for example, transfer and docking stations, varying temperature- or load-dependent geometrical variations make fine positioning essential. The DMP position finder, used especially for fine positioning in the x-axis and y-axis, was developed in order to solve this problem. The device functions using reflectors. It always adapts itself to the actual conditions on-site, ensuring reliable storage, retrieval and docking procedures.
