A sensor circuit for electronically controlled mines comprising a safety insert which arms the fuse, and disarms it again, in accordance with a timing program. The technical problem lies in the reliable object-specific ignition of the mine. Several sensors (B, D, E, F) which respond to signals of different types, which are in a standby position and the output voltage of which is switched to a response signal with a positive signal detection, are connected in series as a sensor chain. The first sensor (B) of the chain is activated by the armed signal of the safety insert and connected to operating voltage. Each subsequent sensor of the chain is connected to the output of the preceding sensor and is activated and connected to operating voltage by the response signal of the latter. The response signal of the last sensor of the chain triggers the fuse (G). <IMAGE>
