Knob cylinder with biometric sensor has biometric sensor mounted on knob that interacts with control electronics and senses a fingerprint for access authorization

摘要

The device has a cylinder housing (13) with a knob (12) rotatably mounted on one side for operating a locking protrusion and control electronics that switch an electronic switching or coupling arrangement in the event of access authorization to make a rotationally coupled connection between the knob and protrusion. A biometric sensor (14) mounted on the knob interacts with the control electronics and senses a fingerprint for access authorization.
