DPE technology
DPE (Double Profile Extended) is a 6+1-pin system. When the key is inserted in the key way, checks are carried out in the cylinder plug by
- a plug rib profile,
- a profile locking bar (which is controlled by a curve in the body; no springs used)
- and an additional control pin.
Benefits
- The special longitudinal profile system is specifically adapted for the cross-section profile retainer and therefore results in strong key cross-sections.
- Large profile cross-sections of 0.5 mm² in the variable profiles guarantee lasting differentiation between the different profile versions.
- The key is precisely centred by the special profile rib design, ensuring the key can be inserted without any difficulty.
- Constant overlapping of a least 4 plug ribs in the scanning area provides optimum picking protection
- Individual differences in profiles are fully effective - no profile variations in the lower key bitting section.
- Modular design
