This is a polypropylene float switch (level switch) to which a reed switch is applied. Ideal for detecting saltwater, hypochlorous acid aqueous solution, etc. Molding was performed twice so that the magnet of the float part was not exposed, and the liquid contact part made of 100% polypropylene resin was realized. Select HL-L3 type when it can be connected to a microcontroller or PLC. For use under harsh environments such as high pressure and UV exposure, we recommend the stainless steel HL-M series.
