Abstract

This assembly includes a system for communicating information by radiofrequency waves having at least one element for transmitting or receiving radiofrequency waves which is associated with the cabinet and at least one element for transmitting or receiving radiofrequency waves which is carried by an implement for receiving products so as to determine whether the receiving implement is inserted into the cabinet or is extracted therefrom. The cabinet constitutes a first element and the receiving implement a second element. The communication system includes at least two elements of transmission or of reception, associated with one of the elements and spaced along a direction (D) intended to coincide with the direction of insertion (S), so as to communicate with at least one element for transmitting or receiving radiofrequency waves which is associated with the other of the elements, in an order representative of the insertion or extraction of the implement from the cabinet.
