<p>The system has a detecting unit with a reader and a coupling unit (20) for transmitting data at a transmission frequency in a contact-less manner, where the detecting unit has a radio frequency identifier (RFID) (63). A shielding unit (47) and a hinge-joint flank (57) interrupt and re-establish the transmission from the coupling unit to the reader, where the shielding unit displays a condition of a door, and is activated by changing the condition of the door. Independent claims are also included for the following: (1) a safety-system with a switching unit (2) a method for contact-lessly detecting a switching condition of a door.</p> |
