This NTI E-LD-LC50-20 Low-Cost Liquid Detection Sensor, Rope-Style - Length of water sensor cable - 50 ft. Length of 2-wire cable - 20 ft. Connect the liquid detection sensor E-LD (E-LDx-y, E-LD-LCx-y, E-CDx-y) to a set of terminals (1-5) marked "DIGITAL IN". The twisted orange sensing cable should be placed flat on the surface (usually the floor) where liquid detection is desired. If tape is required to hold the sensor in place, be sure to only apply tape to the ends, exposing as much of the sensor as possible. At least 5/8" of the sensor must be exposed for it to function.
