The Magnetic Optical Sensor replaces our optical sensor with magnet and offers an improved look, feel, and magnetic design that also lends itself to help prevent water incursion into the sensor.

This sensor plugs into your FMM and, using reflected infrared light, will signal your Apex when it changes state from being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto-top-off), as a high-level warning sensor in your sump, water storage level sensor, and much more. The sensors can be mounted into custom brackets or through a hole in a vessel. Included are a fastening nut and silicone washer.  The MOS’s wire is 5 meters in length
