A sensor arrangement is for mounting along a guidewire or catheter. The sensor arrangement is for positioning along a line of sensor arrangements and has terminal blocks at a proximal and distal side, each for connection to one or more wires. A connection circuit controls the coupling of sensor signals to the proximal wires and the coupling of the distal wires to the proximal wires. In this way, a bypass function is implemented through the connection circuit, which avoids the need for physical wires of a distal sensor arrangement to bypass the sensor arrangement itself.
