Zodiac Jandy Pro Series Slip Sensor 100ft (S2040C) premier A part like this isThis 100 foot slip sensor is made for compatible Jandy Levolor water level control installations that use a slip style sensor. It communicates water level conditions to the controller so the fill system can respond automatically after evaporation, splash out, or normal use. When the sensor fails, the system may stop filling or fill at the wrong time. The S2040C length is suited for moderate cable runs between the sensing point and the equipment pad.
