Appendix C – Cable Lengths
The recommendations in Table C.1 below allow you to provide reliable power to the Smart-
Sensor. The SmartSensor cable’s red and black wires provide a 20 AWG wire pair. The other
pairs on the SmartSensor cable are 22 AWG and are normally used for communication.

Table C.1 – Maximum Cable Length for Power
If the cable length is longer than 600 ft. (182.9 m) when operating at 24 V, it is possible
to increase the maximum cable length by wiring a pair of lines normally used for RS-232
communications with the red and black wires.
