Frequently Asked Questions

The cylinder utilizes a hybrid locking mechanism comprising 7 mechanical key pins and 1 magnetic pin. The plug can only be rotated when a dimple key with the corresponding magnetic code correctly aligns both the mechanical pin tumblers and the magnetic pin element.

No. Physical anti-drilling pins (Φ1.5 mm) in the housing and plug, along with spool pins for anti-picking, are standard configurations. Features such as anti-bumping, anti-breaking, and anti-snap (sacrificial cut) are available as optional selections.

The driver pin hole diameter on this model is Φ2.7 mm, engineered for Φ2.5 mm diameter pins with a 0.4 mm step.

Yes, the 7+1 pin mechanism is compatible with Master Key Systems. Contact our technical department with your keying matrix for specifications.
