CX6122 knob module: double-knob cylinder with one-sided electronic authorisation

CX6122 electronic locking cylinder

The CX6122 consists of the universally applicable Clex knob module which is combined with a profile cylinder with an electronic free-turning knob on one side and a fixed, mechanically connected rotary knob on the other.

The Clex knob module is a universally applicable, battery-powered unit which, for example, is also utilised in the cylinders CX6124 and CX6126 and is already set up for 868 MHz wireless network as standard.

The communication technology, mechatronics and batteries are located in each knob module.

Thanks to the installation of the Clex knob module using a Euro profile cylinder, conventional DIN Euro profile locks can be used and practically no extensive assembly is required.  Thus the double knob cylinder is a cost-effective solution for both new and existing buildings.

The locking cylinder is powered with two conventional CR-2 lithium batteries which can power up to 71.000 locking operations (depending of the transponder technology used). The battery management issues 3 tones before the last closing operations to indicate that the battery needs to be changed. The cylinder can always be powered from an exterior power source using a low power adapter, even when the battery is completely flat.

The broadest range of transponder carriers can be used with the Clex knob module as keys. These include as passive transponders (without power supply): ISO card CX6320, fob CX6330 and alternatively CX6362 as an active function transponder.

The Clex knob module has the following advanced system features:

  • Special time zones/day time activation possible
  • Permanent coupling (toggle function) possible
  • Batteries can only be changed/removed with the right authorisation to open the battery compartment.
  • Simple assembly and dismantling of the knob. This is only possible with the right authorisation.
  • Sealed, water-proof knob in housing up to protection class IP66 (depending on the version)
  • Transponder types:125 kHz: EM4102, EM4450, HITAG 1; 13.56 MHz: MIFARE® DESFire®, LEGIC® prime, LEGIC® advant, active transponder (868 MHz)
