Home Products DPX locking cylinders General Information DPX represents an innovative locking technique with 4 independent security levels. This means maximum security for all applications at minimum cost. How does it work? The combination of a special length profile with 2 independent side profiles results in 34 million different profile variations. The access authorisation is checked by the plug ribs profile, by the 2 side bars with integrated control pins and the pin tumblers. Your advantages 4 independent security levels: 1 length profile, 2 side profiles and pin tumblers The length profile is specially adapted for 2 side profiles Picking protection through constant and 4-fold overlapping plug profile in the whole pin area. In addition mushroom pins prevent the pressing and falling through of the pin tumblers Long lasting differentiation of the profiles through large profile cross sections of minimum 0.5 mm Drilling and plug pulling protection through an U-segment made of hard metal and two staggered hard metal pins on each cylinder side High wear resistance and long durability through special plug pins and spring less operating side bar Technical (key manipulation) and organisational (security card) key protection Legal key protection through patents: e.g. Euro-Patent-No. 0566.701, Austrian Patent-No. A2217/91*, USA-Patent-No. 5797287 and DEGM G91 15 223.2   [ Back ]
