MOS Magnetic Optical Sensor – Neptune Systems

Product details

MOS Magnetic Optical Sensor – Neptune Systems is a replacement optical water-level sensor for Neptune Systems Apex controllers. It plugs into an Apex FMM port and uses reflected infrared light to detect when the sensor’s state changes from wet to dry or dry to wet. The result is an easy way to add dependable level detection for applications like auto-top-off (ATO) control, high-level warnings in a sump, or monitoring a water reservoir level.

Features:

• Replaces the previous OS-1-M with an updated design for tighter installation spaces
• Uses reflected infrared light to detect wet/dry state changes for your Apex
• Plugs into an Apex FMM port for straightforward integration with Apex systems
• Includes a built-in magnetic mount for attaching the sensor to a reservoir
• Silicone-encased external magnet helps protect the mounting area and supports reliable attachment
• Compact form factor designed to fit into tighter sump and reservoir locations
• Completely waterproof for safe aquarium and sump use
