Compact double-knob cylinder

The compact knob cylinder is an electronic locking cylinder, which is characterised by its compact size and numerous versions. The compact knob cylinder is also suitable for electronic access control on narrow frame doors because of the small handle diameter of 33.0 mm. The identification can be done by a passive transponder or by an active transponder with its own power supply.

The product offers additional advantages through its special security features. All the security components, such as the coupling, gears and motor are located in the protected area in the cylinder. The electronics and cylinder are rigidly coupled, the electronics unit is safely housed in the core of the cylinder. A mechanical drilling protection is also integrated by default. These security features additionally characterise the compact knob cylinder as a security cylinder.

Different versions make this product particularly flexible, for example, the version as a half cylinder or the anti-panic version. The version for outdoor use with protection class IP66 also allows it to be installed outdoors and in building exit doors. The security version characterised by an advanced drilling and pulling protection is especially suitable for this purpose.
