Optical Sensor with Integrated Magnet

Magnetic Optical Sensor for Neptune Apex

The Neptune Magnetic Optical Sensor replaces the 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.

The MOS 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 with the Neptune MOS are a fastening nut and silicone washer.
