Electronic double-knob cylinder

The double-knob cylinder is an electronic locking cylinder with a two-sided separate electronic authorisation. The evaluation electronic system is located in the protected interior. The locking cylinder is also suitable for use in building exit and external doors.

With the double-knob cylinder, access is controlled electronically from both sides of the door. Different access rights can be issued for both sides.

A version with additional mechanical drilling and pulling protection, as well as a version for outdoor use with protection class IP66 are available. The identification can be done by a passive transponder or by an active transponder with its own power supply (not in the system Clex public).
