<p>A proximity sensor system (1) comprising a proximity sensor device (3) and a conductive area (5) external to the device, the latter being able to increase the sensibility (and therefore the operating range) of the proximity sensor device (3) with high effectiveness and low cost. The external conductive area (5) can be of any size, shape or configuration, although preferably comprising a structural support (4) that is connected to the proximity sensor device (3) in such a way that the conductive area (5) becomes connected to the conductive element (6) of the proximity sensor device (3). The conductive area (5) then acts as an extension of the aforementioned conductive element (6), therefore allowing to obtain a long-range proximity sensor system (1) at a reasonable price.
