Jandy Half Moon Style 2 Contact With 100' (skimmer install)

The Jandy Levolor Half-Moon Style 2-Contact Sensor with 100-Foot Cable (Model S-200-100 / Part # R0658501) is an electronic water-sensing probe designed for direct skimmer throat mounting requiring an extended cable run between the pool and the equipment pad. It pairs with Jandy Levolor electronic water level controllers (such as the K-1100 series single-zone fill systems) for in-ground pools and spas.

Its curved, semi-circular profile mounts flush against the contoured interior wall of standard pool skimmers, eliminating the need to plumb an external static standpipe or core through pool decking. Two solid-state stainless steel contact pins detect water presence via electrical continuity without moving float parts. When water recedes below the lower pin, the open circuit signals the Levolor control box to initiate a fill cycle after an integrated wave-delay sequence.

Key Specifications

Skimmer Installation Overview

1. Mounting Location: Clean and dry the curved inner wall of the skimmer throat below the weir gate assembly.

2. Height Calibration: Position the bracket so the lower contact pin aligns with your desired fill cut-in point (typically midpoint of the skimmer opening).

3. Cable Pull: Feed the 100-foot shielded cable out through the skimmer's top access or auxiliary port and pull through dedicated low-voltage conduit back to the equipment pad.

4. PCB Termination: Connect the two sensor wires to the designated low-voltage sensor terminals on the Levolor main board.
