Longer switching distances of up to 20 mm, integrated evaluation intelligence in the reading head, wear-free semi-conductor outputs, and the possibility of cascading several systems in a row are the principal advantages of the new T 4000 Compact electronic safety interlocks. The system, corresponding to Control Category 3, thus opens up new opportunities in safeguarding movable delineating protective structures.

Automated guided vehicles (AGVs) with a future are increasingly leaving guide cables behind - and can thus be used more flexibly. This has been made possible by new technologies for guiding vehicles, e.g. SICK´s NAV 200 positioning system.
