FineTek FDM Mini Float Level Switch

Finetek FDM series is a magnetic float level switch type of product line that is very compact and cost-effective. These mini magnetic float level switch devices operate based upon two scientific principles, buoyancy and magnetism. The float portion of the mini float level switch is designed for a specific minimum fluid density, specific gravity, based upon the float element’s volume and weight. The float contains a magnet, and the stationary stem incorporates a reed switch that opens or closes its electrical contact when the magnetic element in the float comes in contact with the stem. The reed switch reverses its contact state when the float element’s magnet moves away from the stem.
