Compact Electronic Knob Cylinder


Modern and flexible


The compact knob cylinder from Uhlmann & Zacher in a modern stainless steel design replaces a mechanical locking cylinder. The door is opened using transponders, for example cards or fobs. In addition to new buildings, existing mechanical locking systems can also be replaced with the modern wireless access system.


Perfect for tubular frame doors


The handle diameter of the electronic knob is 33 mm. Thanks to these compact dimensions, the electronic locking cylinder is ideally suited for use on tubular frame doors. In addition to these, it can also be installed in many common wooden doors, plastic doors and glass doors.


Security features


The cylinder impresses with its safety features. All safety-relevant components such as coupling, gears and motor are protected in the cylinder core. The electronic knob and the cylinder housing are firmly connected to one another. A version with an additional mechanical drill protection is also available.


Energy efficient


The compact electronic knob cylinder is characterized by a long battery life of up to 70,000 openings with just one battery.
