System with many functionalities. The Han-Yellock® interface consists of a bulkhead mounted housing on the cabinet side and a carrier hood with cover on the cable side. The locking ability is a key function of the Han-Yellock®. The function makes connections and disconnections safe, simple and quick – even under harsh industrial conditions. One Han-Yellock® feature is a patented internal locking mechanism like the seat belt. The locking takes place as the cable and device sides are simply joined together. The hoods/housing are not mating compatible with other Han® hood/housing series. By using the Han-Yellock® modules, only male contacts are needed and in addition the PE terminal can be assembled with crimp or Han Quick-Lock® termination. Modules from the Han-Modular® series will be used in combination with the Han-Yellock® adapter frame.The Han-Yellock® system can be used with a variety of inserts in order to establish flexible interface possibilities.
