No. Cables are attached and sealed on the sensor by the manufacturer. Whenever possible, purchase a sensor with the desired cable length. Alternatively, a new sensor can be purchased with a foot of cable and then spliced onto the existing cable. Splicing cable together, however, increases the likelihood that water may enter the cable and cause shorting, corrosion, and some other potential issues, which in turn can cause measurement issues. Because of the potential issues, do not splice any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.
