Sensor connections can be used in single-ended or differential mode. Single-ended only needs one cable per connection but is susceptible to noise (1) as well as errors due to ground loops (2).
Differential connections use two wires where the signal is “mirrored”. The two signals are compared by an amplifier and only the signals that are opposite to each other count as valid.
This makes it insensitive to noise since the noise affects each signalling line in the same direction.
