OS-1 Optical Sensor

What It Is

An optical wet/dry level sensor for compatible FMM inputs.

Why We Like It

Useful for detecting a specific high or low water level when you already have a suitable mounting point.

Key Specs

• Point-level optical sensing.
• Sensor accessory; not a complete ATO.

Requires compatible input and mounting arrangement. Check whether a magnetic bracket is included; do not assume one.
