Various float sizes and materials cover many different applications.

Features

Reed switch makes 10 million times use possible
Applicable to many different liquids as SUS304 (SUS316, SUS316L) and corrosion-resistant resin are used for the wetted surface
Lots of operations are selectable. Multiple points are detectable by adding the number of reed switches
Not affected by moisture, gas, dust etc
Easy handling with simple structure
