Pick-up devices (1-9) for picking-up signals from first cables (21, 22) in electrically contactless manners comprise first arrangements (31) for picking-up power signals from the first cables (21, 22) in inductive manners and second arrangements (35, 36) for picking-up data signals from the first cables (21, 22) in capacitive manners. The first arrangements (31) may comprise inductive couplings such as magnetic cores (61, 62) with first openings for surrounding parts of first conductors (21) of the first cables (21, 22) and with second openings for surrounding parts of second conductors (22) of the first cables (21, 22). The second arrangements (35, 36) may comprise capacitive couplings such as first and second electrodes (71-74). The pick-up devices (1-9) may be pick-up and transfer devices (3) for transferring the signals to second cables (23, 24) in electrically contactless manners. Provision devices (10) provide the signals in electrically conductive manners and termination devices (11-13) terminate the cables (21-24). |
