WCS* Read Head Position Encoding System
Product Description
2.2 Areas of Use
The WCS can be used anywhere where material handling equipment has to be positioned pre-
cisely. The operating principle of the WCS enables it to be used in a diverse range of applica-
tions, including:
• Interruptions in the code rail
• Applications with curves and circular paths
• Use of multiple vehicles in a row
Due to the large tolerance between the read head and code rail, the WCS can be used for most
applications. In some cases, however, it is advantageous to use the WCS with a special protec-
tive enclosure or a guide trolley in conjunction with the aluminum profile system. Here are some
examples from the variety of application options:
Automated Storage and Retrieval Systems (High-Bay Warehouses)
Moving carriages, lifting gear, and transversing carriages are each positioned with one read
head. The positioning is independent of the length of the code rail and always absolutely repro-
ducible. For new high-bay warehouses we recommend the WCS3 system. For retrofits in older
warehouses, it may be beneficial to use the WCS2 in conjunction with the aluminum profile sys-
tem:
• Easy to retrofit
• High mechanical tolerances between the measuring system and moving carriages possi-
ble
• Decoupling of vehicle vibrations
