Abstract (en)
[origin: EP0516611A2] A locking cylinder (1) can be blocked by a key (15) having a mechanical code track with a height profiling at a plurality of height levels (27, 28, 29) identifiable on the lock side by a reading device which comprises an analog transmitter, for example a pressure-variable resistor, especially rubber resistor (19), in a measuring circuit (20). When the key (15) is inserted into a key channel (14), the code track is sensed by a tracer pin (13) and the code-dependent measurement quantity, for example the resistance values variable as a function of pressure, are detected in succession. They result in a code which is compared with the code of a code memory (22). If the codes agree, a release signal for an electromechanical locking device (26) is generated. Furthermore, the locking cylinder (1) can additionally have the conventional pin tumblers (4, 5, 6, 7, 8). <IMAGE>
