S2044C | Jandy Pro Series Half Moon Style 2 Contact 100' for Skimmer

The Jandy S2044C is an OEM Half Moon Style 2 Contact water level sensor with 100 feet of lead wire, designed for skimmer-mount installation with the Jandy Pro Series Levolor automatic water leveling system. The half moon sensor installs inside the pool skimmer and uses two electrical contacts to continuously monitor pool water level — when water drops below the set point, the circuit opens and signals the Levolor controller to activate the fill valve, automatically restoring the pool to the correct water level. The 100-foot lead wire accommodates installations with moderate distance between the skimmer and the Levolor controller, making the S2044C well suited to most standard residential pool equipment pad configurations. A failed or degraded sensor is one of the most common causes of irregular filling, no-fill, or overfilling symptoms in Levolor-equipped pools, making timely replacement an important troubleshooting step. The S2044C replaces legacy Jandy part numbers 4350-016 and 902546.

Highlights

• Factory-Authorized Jandy OEM Sensor: Manufactured by Zodiac/Jandy to exact Levolor system specifications, the S2044C half moon water level sensor delivers reliable, accurate level detection and seamless integration with the Jandy Pro Series Levolor automatic fill controller, supporting consistent fill behavior across daily pool operation.
• Half Moon Profile for Skimmer Mount: The half moon sensor profile is specifically designed for installation inside the pool skimmer and secures in place with small plastic spring clips that seat under the skimmer's interior lip, providing a clean, unobtrusive installation that keeps the sensor entirely out of the main pool plumbing.
• Two-Contact Level Detection: A pair of electrical contacts continuously monitors pool water level, and when the water drops below the set point the circuit opens and signals the Levolor controller to activate the fill valve, automatically restoring water to the correct level without requiring manual intervention from the homeowner or service technician.
• 100-Foot Lead Wire Run: The 100-foot wire provides ample reach for most standard residential pool equipment configurations, bridging the distance between the pool skimmer and the Levolor controller location on the equipment pad without forcing the installer to add wire extensions or run additional conduit during installation.
• Replaces Jandy 4350-016 and 902546: The S2044C is the current Jandy OEM replacement that supersedes legacy part numbers 4350-016 and 902546, making it straightforward to confirm the correct replacement sensor across older Jandy parts references, service documentation, and distributor catalogs.
