Miniature Float Sensor

Main feature

Extremely small

Even smaller and lower cost than our OL sensors.

Stable operation

The float is designed not to stick to sensor body and hinder correct operation, which tends to happen with small floats.

High reliability

Among high accuracy reed switches, only those that meet our original standards are used to ensure stable operation over the long service life.

Principle of Operation

The stem has a reed switch at a set point and the float incorporates a magnet. The reed switch opens or closes as the float goes up or down on the stem, indicating a level.
