Digital sensor for a CAN network of a vehicle, comprising a casing (4) which comprises a first portion (56) provided with a housing (60) capable of receiving a first electrical cable (8) and a second electrical cable (10), said first portion (56) receiving a first electrical component (24) and a second electrical component (26) respectively arranged opposite said housing (60), and which first electrical component (24) and second electrical component (26) each have a substantially flat surface adapted to constitute a capacitive element with respectively a portion (14) of said first electrical cable (8) and a portion (16) of said second electrical cable (10), such that, when said first electrical cable (8) and said second electrical cable (10) are received in said housing (60) and each carry a respective CAN digital signal, said first electrical component (24) and said second electrical component (26) carry an electrical signal corresponding to the digital CAN signal respectively carried on said first electrical cable (8) and on said second electrical cable (10), and a second portion (58) receiving an electronic circuitry (6) connected to said first electrical component (24) and said second electrical component (26), and arranged on the one hand to process the electrical signals which they carry in order to rebuild a first analogue signal and a second analogue signal which reflect the digital CAN signal respectively carried by the first electrical cable (8) and the second electrical cable (10), and on the other hand to transform the first analogue signal and the second analogue signal into respective digital CAN signals towards an output (12) connected to said electronic circuitry (6). |
