Float Sensor Switch For Water Level Controller

Description:

The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. Most float switches are "normally closed," meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point, resting on its bottom clip or stop (for example, when a tank is dry).

Since this sensor acts as a switch, this can be useful to turn on or off a pump, or raise an alarm when the water level goes lower than the level etc.

Depending on the application, the condition of the float switch can be changed from normally open to normally closed or vice-versa depending on the placement of the float operation.

This float sensor uses magnetic topology where a magnetic reed sensor is placed inside the sensor. Based on this magnetic reed sensor, the float sensor could achieve 0.5A of switching current at 100VDC.

Please use a Relay or other type of switching devices along with this sensor to switch high load applications.

Pinouts:

This float sensor acts like a switch, thus not having polarity and can be used in either directions.
