The EPB series provides polypropylene float components with an internal annular magnet. The float follows the liquid surface and its magnetic field actuates a compatible reed switch in the sensor assembly. These components support replacement and integration in water-level systems, small tanks, humidifiers and other liquid-sensing equipment.
PP construction offers low weight and compatibility with water and selected weak acid or alkali solutions. Check the complete float’s chemical compatibility and the liquid density for the intended service.

Select the bore for the guide stem, then check outside diameter, height and available travel. Match the magnet to the reed switch sensitivity and required operating position. The float requires a compatible sensor assembly to produce an electrical output.
Specify the model, liquid, temperature and magnetic requirements when ordering. For the additional NBR001 dimensional option, the reference dimensions are 48mm outside diameter, 20mm bore and 22mm height; confirm its material and service rating separately.
